Written by Brian Wilson, Mike Love, and Gary Usher. Released in 1962 on the Surfin’ Safari album and in 1963 on the Little Deuce Coupe album. Gary Usher says:
Dennis Wilson was the first Beach Boy to pick up on surfing. He was aware of Dick Dale, the Pendleton jackets and that whole shot. It just rubbed off. I never surfed. I was a hot rod freak. I had a 409. One day we were driving up to Los Angeles looking for a part for my car, and I said ‘Let’s write a song called ‘409’. We’ll do a thing ‘giddy up, giddy up,’ meaning horses for horsepower,’ just kidding around. We came back and put it to three simple chords in five minutes, and it developed into a million-dollar car craze.
