Waitresses. I couldn't find a video of the band performing this song, but the audio on this one is pretty good and the cheesy light display sets it off in a festive way.
If you're "of a certain age", you'll remember the The Waitresses did the theme song from the short lived 1979 sitcom "Square Pegs", starring the gawky, nerdy, teen-aged Sarah Jessica Parker as a gawky, nerdy teenager trying to fit in with the popular kids. I think it's safe to say she finally made it over the hump.
