Tress MacNeille is one of the modern generation's best known voice actors, but did you know she actually appeared in a music video? Not only that, she also "sang" on the accompanying record.
The song in question is "Weird" Al Yankovic's "Ricky", which mashes together Toni Basil's 1981 hit, "Mickey", with the classic sitcom, I Love Lucy. In the video, Al plays a dual role, appearing clean shaven as Ricky Ricardo (Desi Arnaz) opposite Tress as Lucy. Tress actually did go into the studio to record the track with Yankovic, and that, friends, might be what got her started on a successful voice acting career. Al also appears as himself with his band in scenes that were taped separately.
Before anyone asks, I think another actress was hired to play Lucy, or an analogue thereof, six years later for Billy Joel's "We Didn't Start the Fire".
