Benny Goodman – “Sing Sing Sing (With A Swing)”
Live At Carnegie Hall

I came across this track completely by accident while looking for the more conventional dance hall version of this song, but after putting it on, sat in shocked rapture for the entire 12 minutes. The breakdowns and rebuilds, the departures and returns to the original melodies, the unbelievable playing. I wish I could hear what he says that makes the audience laugh nine minutes in, though. And man do I wish I was there that night in 1938.
