(Jazz) Can anyone identify this Lee Konitz tune?

Youtube has labeled this Ronnie’s Tune but I’m pretty sure that’s wrong, because several other Youtube videos of Lee Konitz - Ronnie’s Tune are a different tune.

So what’s this one? It’s great, isn’t it? That duet out-head is amazing (I think it’s two Konitzes, overdubbed).

Yes, that’s great. No, I don’t know what it is, sorry.

I got to see Lee in a trio with Paul Bley and Steve Swallow. That was just about the best show ever.

I’m pretty sure it’s Lee Konitz and Warne Marsh cutting Ronnie’s Line:

Ding ding ding! You must be 100% correct. Thank you!

Track listing below, with audio samples. That’s it for sure.

I like the Lee Konitz and Warne Marsh recordings. Konitz is a terrific improviser, and Marsh is a unique talent. They’re both COOL
