I was looking at the listing for the "X-Men" 1992 TV series at the IMdB, (Internet Movie Database), when I came across this bit of information for the episode "Repo Man". Melissa Sue Anderson is listed as the voice of Snowbird in the two Alpha Flight episodes, ("Repo Man" and "The Phoenix Saga, Part 5").
I wonder what happened? One thing's for sure: she definitely couldn't have been worse than the voice for Puck!
