Having started out as The Rovell Sisters around 1958, in 1963 and 1964 The Honeys released a number of singles written, arranged, or produced by Brian Wilson. The Honeys' career faded as surfing music went out of vogue. Marilyn and Brian were married and became the parents of Carnie and Wendy Wilson, who later found fame as members of Wilson Phillips.

Marilyn and Diane Rovell, also formed the group Spring (known outside the US as American Spring, due to another band with the same name).
