they actually didn't cover that song... and here's why i know:
Q. is this song a weezer song?
A: songs titled "break my heart" "drive around the world in my car", "we have a technical" (the rentals), "california" (the rentals), "texas", "internet girl", "tomorrow may come" "rainbow of love" "no other girl" "please let me get what i want" (smiths cover)"congratulations" (special goodness), "x-girlfriend", "mrs robinson"(simon&garfunkel OR the lemonheads), "paint by numbers"(self), "uptown girl" (billy joel cover), and "game over"(ozma) are misnamed songs floating around the net. they are not weezer. also, there is no hidden track on the green album - somone misnamed an mp3 from ozma's "baseball" on the net.
that was taken from weezer's web site.
