I've always thought the Rolling Stones' sound was more influenced by the Everlys than the Beatles sound was ...
BTW, the cd reissues of the mid 60's Everly albums, with sound by Bill Inglot, seems to have been set back a year or so.
But the 1983 Everly Reunion concert at Albert Hall is due out on DVD this January! If the 1985 Chuck Berry Concert (the one with Etta James, a Stone, etc), could get a DVD issue, my little classic collection would take a giant leap forward.
