Snoopy, the Red Baron, and aircraft became a recurring theme in their songs, though they did have some chart singles without those themes, including "Any Wednesday", "I Say Love", and the Top 40 hit "Baby Let's Wait", a re-release of their first single. The original group split in 1969, but a band with some replacement players continued for another year. Two compilation albums and the original albums (doubled up) have been released on compact disc.
