In Keith Badman’s book The Beach Boys: The Definitive Diary of America’s Greatest Band on Stage and in the Studio, the “Wichita Lineman” singer admitted that he didn’t know the words, but it didn’t matter much.<\/p>\n
“The only problem was, I didn’t know all the words to the songs. They’d be singing ‘Pasadena,’ and I’d be singing something else. I didn’t know what I was saying. But the screams were so loud from the girls, you’d walk onstage, and you couldn’t hear a thing anyway.”<\/p>\n
Wilson and Campbell collaborated on the song “Guess I’m Dumb,” released in 1965. The song, written by Wilson and Russ Titelman, was rejected as a Beach Boys song. When it was rejected, Wilson shared it with Campbell.<\/p>\n
“Brian [said], ‘Glen, you want to sing it?’ ” recalled Campbell<\/a>. “I said, ‘Sure, I do.’ Because I kind of liked it. It was a great track, and the guys already had some background on it.”<\/p>\n Brian and Carl Wilson both lent their voices to the song.<\/p>\n Never miss a story \u2014 sign up for PEOPLE’s free daily newsletter<\/a> to stay up-to-date on the best of what PEOPLE has to offer, from celebrity news to compelling human interest stories.<\/p>\n Brian Wilson The next time Wilson and Campbell would work together was after Campbell died.
