Yes, Simon sure opens the taps at the end of that number. I'd completely forgotten about Rocks, pebbles & sand. Great album.
Here's a classic piece of Simon playing. Yes, he's into his trademark boogie, but this is pretty much a jam situation, & displays Simons listening skills superbly. Hear how he immediately tunes into the vibe of each players solo spot on the fly. A few egos on that stage too, so not an easy task politically :) http://www.youtube.com/watch?v=MEaTWe0h0u8
