Michelle Aller sang back-up on albums by Dusty Springfield and Cher in the 1970s.

(which she co-wrote, billed as Aller). She did similar double duty for the 1978 Rollerboogie film soundtrack (as Michelle Aller for songwriting and Mavis Vegas Davis for performance) and appeared in the 1988 film Salsa.

She later moved into television, largely as a stage manager but occasionally performing, including as a backup dancer in the Minnie Mouse special Totally Minnie and two appearances on the short-lived TV series Hull High as a singing janitor. She was stage manager for Joan Rivers on The Late Show, Saved by the Bell, American Idol, and various specials.
