Roger Waters singing "If" live?

I'm reasonably sure this question's probably been answered or at least addressed at some point in this forum's existence, but obviously the song title "If" makes it almost impossible to search for.

Basically, what I'm curious about is if there's ever been a recording, illegal or otherwise, of Roger Waters performing "If" live in concert during one of his solo tours. I'm not asking anyone to do anything shady/against forum policy, but it's such a great song (one of my favorites for sure) and I read that he did perform it on occasion. I'm just wondering if searching for it would be a complete waste of time or not heh. Thanks.

Why yes, there is quite an excellent bootleg video from the KAOS tour! Unfortunately that specific song is split into two parts on YouTube. It was also played each night of the Pros and Cons tour, so there are audience recordings with Eric Clapton on lead guitar...

Ah thank you very much! I knew I could count on someone here to help me out! It's a shame that it's spliced in the middle there but it's still great to hear/see it anyway. Thanks again.
