And of course, there was always "Strawberry Alarm Clock"

From Wiki:

The group originally consisted of Ed King (lead guitar), Mark Weitz (keyboards), Lee Freeman (rhythm guitar), Gary Lovetro (bass), and Randy Seol (drums). On their first and most famous single, "Incense and Peppermints", none of the band wanted to sing songwriter John Carter's lyrics, so lead vocals were sung by Greg Munford, a 16-year-old friend of the band, although the regular vocalists sang backup. The song reached #1 on the Billboard pop singles chart in late 1967. Mark Weitz and Ed King were denied songwriting credit by the band's producer because they did not write the melody line or the lyrics, though the song was built on an instrumental by Weitz with a bridge by King originally intended as a B-side to "Birdman of Alkatrash," which ultimately became the B-side to "Incense and Peppermints." The original composition that became "Incense and Peppermints" was titled "The Happy Whistler."
