Zeppelin and Pink Floyd are both fine bands. Excellent in their own rights.

I know more about Zeppelin because I began following them in 1969, with LZ II, when I was just 14, and I didn't get turned on to PF until 1973 with DSOTM.

I have seen Zeppelin in concert, but I never saw PF in concert. I would have in 1977 for the Animals tour, for sure, but I was broke, after seeing Zeppelin 3 times that year !!!
Oh well..

I ran across a YouTube video which has (audio) studio outakes from Led Zeppelin's work on "Heartbreaker" from the LZ II sessions. It really takes you back to that special time and place in 1969. Of all the big bands in the world that have filmed their work in the studio, we have the least from Led Zeppelin. I don't know if their is any Zeppelin studio footage. But The Beatles, The Stones, The Who, and, Pink Floyd, all delivered there..
