Grover Washington Jr. on tenor sax! A pioneer of the smooth jazz genre, which isn’t my favorite style, but some of it sounds pretty good.
Adrian suggested that I check out this song again, so I have.
His group lays down a really solid groove on Mister Magic which came out on his album in 1974. Saw it on youtube and noticed that Amy Winehouse did a version of it too, seemed like from the comments that people liked her version a lot – comments about the solidity of the groove and whatnot.
