Don't forget that a HUGE number of hit songs with intricate guitar parts from hundreds of bands had Glen Campbell playing them. He was an anchor member of the wrecking crew. The wrecking crew actually recorded most of the hits you heard on the radio, including standards, rock, country, blues, etc. Just about anything from 50s, 60s, 70s, and 80s were the wrecking crew. Maybe even much later. Hal Blaine even did 99% of the Beatles Drum tracks. Eric Clapton did a lot of the Beatles guitar parts as well. Carol Kaye played bass on well over 10,000 songs. Hit records are not what they seem.
