I bought Pet Sounds in the 80s after reading numerous interviews in which McCartney praised the album -- and Wilson's supposed bass playing on it. I later heard it was Carol Kaye on the bass. More recently, I read a book about the Wrecking Crew -- from which I learned that Kaye was one of numerous bass players on the album. There's a childlike quality to the songs. However, I do not see Pet Sounds as a rival in quality to any Beatles album, as much as McCartney may have been inspired by it.
