I’ve got a book on Fender amps, and it has pic of a very young Glen Campbell in the studio playing guitar when he was working as a session musician. The guy is a super talented guitarist, and if you think guys like Chet Atkins or Eric Clapton are the only ones who can play, you need to check out some of the clips on Youtube with Mr. Campbell tearing through some songs.
Yesterday I sent this link to my brother....he came back with the comment that as-yet unknown Glen Campbell had been the entertainer at their 1963 high school graduation banquet in the Los Angeles area......it was shortly thereafter that he started getting recognition and “real” gigs.
