The Turtles’ 1967 hit “Happy Together” knocked The Beatles’ “Penny Lane” out of the number one slot for three weeks on the Billboard Hot 100, and became the group’s only chart-topper. The song had been rejected a dozen times before it was offered to The Turtles, and the demo acetate was worn out.
When performing the song on television, leader Mark Volman commonly “played” a different instrument not present in the song for each appearance. On Ed Sullivan he “played” a trumpet, on the Smothers Brothers a piano, and on others a French horn. This could be seen as a wink to the audience that they were lip-syncing, a common practice for 1960’s television.
