Regarding the first two Columbia albums, "Mr. Tambourine Man" and "Turn, Turn, Turn", I recall reading an interview with David Crosby where he states that only Jim (Roger) McGuinn played on the first two albums, that Terry Melcher contracted many of the Wrecking Crew members--Blaine, Kaye, Tedesco, Campbell, Knechtel, and others, to lay down the basic tracks; then McGuinn would overdub 12-string electric guitar and all vocal leads and backgrounds would be added by all except Michael Clarke. When "Third Dimension" was recorded, Columbia exec Allen Stanton produced the album and utilized the same musicians, which gave basically the same sound. Then came "Younger Than Yesterday" which yielded a much rawer, "clunkier" sound, due to the Byrds finally being allowed to play their own instruments on record. This is not unlike the Monkees' "Headquarters", where they also began contributing to the music. I hope this clarifies some of the misunderstandings and myths about the Byrds playing on their first few outings. One thing for sure, The Byrds' albums are classics that deserve Steve Hoffman's touch!
