The quality of this cover only makes me marvel at Gilmour's improvised version all the more.
It takes a virtuoso guitarist to approach what Gilmour did on the spot.
Absolutely, that's what my quote in signature is all about: “It was easy to be great. What was hard was to be good.” — Steve Martin
Meaning that you can copy David Gilmour's solo exactly, but the man himself can produce 10 solos like that night after night and actually make a living out of it. I think we often deeply underestimate just how great all the greats are.
