Has Pink Floyd ever covered songs live?

Hey everyone, this is my first post in the forums. Anyway i was wondering, has Pink Floyd ever covered a song in concert? I was talking to my friend about it who claimed that every band has covered songs at some point. I couldn't think of any off hand, even in some of the earliest shows, but who knows. Input would be greatly appreciated.

I think i got a version of knocking on heavan's door. really sounds like waters singing but im not sure.

Also tribute song to john lennon on a tv show, one of his songs.

yeah, roger has covered "knocking on heaven's door" as well as "across the universe" in 1987 or something.

Other than that, I don't know of any PF covers.

Early on before they were known as Pink Floyd and possibly before Syd was in the band they played a lot of old covers. I don't think they ever played a cover live in concert as a band though.

The post-Roger Floyd actually played a few low-key gigs as a cover band called The Fisherman's. They even played "Rapper's Delight."

I can't make this stuff up.

My band covered a Floyd song once...

Pretty much the same thing.
