Every jam on this site has a start time: the second the composition ends and the improvisation begins. For most songs that line falls early in the track. You Enjoy Myself is the great exception. Across 546 hand-tagged versions, the jam doesn’t begin until a median of 7 minutes and 52 seconds in. Before Phish improvises a single bar of YEM, they’ve already played a song longer than 70% of the songs they play.
The longest wait in the catalog
Put YEM’s runway next to the other vehicles people think of as long. Harry Hood reaches its jam at 5:33. Reba at 6:24. Stash at 5:02, Tweezer at 4:40, Down with Disease at 3:50, Mike's Song at 2:34. Only Divided Sky makes you wait longer, and Divided Sky’s jam, while consistently beautiful, is typically short.
To put it concretely: there are 51 songs played forty times or more whose median full length is shorter than YEM’s introduction. A whole Mike's Song. A whole Weekapaug Groove. A whole Chalk Dust Torture. Each one, beginning to end, is shorter than the runway YEM gives you before liftoff.
The runway got longer — then it locked
The wait wasn’t always this long, and it wasn’t always this exact. The composed section creeps up year by year: roughly 6:54 in 1989, a clear step up in 1993, peaking near 9:20 in 1999. Since then it has settled around eight minutes. The more striking number is the spread. Early YEMs scattered across a full minute. Modern ones land within about twenty-five seconds of each other, night after night.
It isn’t only where the jam lands that’s consistent. The composed section sits at a near-immovable 99 BPM in every era of the band’s career. The jam is where they let the tempo move; about three versions in four speed up once they cross the line.
The marker sits where the composed instrumental gives way to the bass-and-drums jam. The vocal jam counts as part of the jam, not the composition. Only standalone YEMs are included; segued fragments and teases are excluded. All 546 versions are hand-tagged, one at a time.
The anatomy of an average YEM
Average all 546 versions together, normalize each one to its own length and loudness, take the median energy at every point, and a single, repeatable shape falls out. YEM is a two-peak song. The composition climbs to a loud climax about a quarter of the way in, eases off, and the jam-in lands in the valley that follows. The jam then builds a second, taller peak around two-thirds through, before the vocal jam carries it down to the close.
Then anything happens
Past the marker, the discipline evaporates. The median jam length is 10:50, but the tail is enormous. The 10/31/95 Rosemont YEM jams for 32 minutes. The 12/9/95 Albany version, our highest-scored YEM, runs a 25:42 jam. The mid-’90s were the golden age of the long YEM. The band never abandoned the form, but they stopped chasing the half-hour version. Now it’s a fixed eight-minute runway and then open sky.
This is the version the numbers keep pointing at: 12/9/95, Albany. Press play; we’ve cued it to the jam-in at 8:40.
And the one the scatter plot can’t stop pointing at: 10/31/95, Rosemont. A thirty-two-minute jam, the longest in the dataset.
For contrast, a modern one: 8/30/24, Dick’s. Same composition, hit to nearly the same second as every other recent version, and a 19-minute jam: long, but nowhere near the ’90s monsters.
The barometer
If you’re choosing a show to put on, this is the part that matters. The longer a YEM’s jam runs, the better the night tends to be. Sort every tagged version by jam length and the median show score climbs from the low 20s for the short ones to the high 60s for the eighteen-minute-plus monsters. The correlation is 0.41. Some of that is circular (a huge YEM helps make a show great) but the signal is strong enough to use. If the YEM stretches out, you’re almost certainly in for a special show.
What it grew into
As the song got longer and more exact, the band started treating it differently. Early on, YEM was a workhorse. It opened sets, closed sets, turned up almost anywhere. Over time it migrated into the second set and stayed there.
And the second-set versions aren’t just more frequent. They’re also bigger. A set-two YEM jams a median 12:06 and runs 20:08 end to end. A set-one YEM jams 9:28 and runs 16:49. When the band holds it for the second set, they give it room.
They also play it less. In 1990, You Enjoy Myself turned up in more than half of all shows. In the modern era it’s closer to one in seven. The more it became an event, the more they rationed it.
One twist hides in the quality numbers. Every one of the longest, most celebrated YEMs predates 2000, and yet the typical modern version scores higher than the typical ’90s one. The ceiling came down. The floor came up.
So what
YEM is the only song in the rotation that is, at the same time, a composition showcase and a marathon jam vehicle. Almost everything else is long on one end or the other. YEM is long on both. The composed half has quietly become one of the most precise things the band does, and the jammed half remains one of the least predictable. They build the same eight-minute machine every night, and a few times a year now instead of nightly, they let it fly.
Stack every You Enjoy Myself ever captured end to end and it comes to about 177 hours. More than a week of continuous YEM, at a median of nearly nineteen minutes apiece. No other song in the catalog asks for, or repays, that kind of patience.
