So looks like just me and Bimbo had the good taste to pick Steve Cropper :-)
Now I know this is about favourites rather than best but the fact that only one other person had Buddy Guy in their list caused me some sadness; but then I saw that he is below Bernard (and i say this as someone who has seen New Order more times than any other band) and JDB in this list and my sadness turned to rage as frankly this is a crime against music!!
But more seriously, if you like bluesy stuff at all and you are not familiar with him check him out, Buddy is in his mid 80's now and is still going at it. The people he got to guest on his 2022 album tells you all you need to know about the esteem in which he is held. Absolute legend.
Glad to see Duanne Allman in the list, one of the great "what could have been"s of popular music.
