Oh I don't know, I think it would actually be kinda kewl! I mean Creed did do a cover for them, why not the other way around? Maybe then people can say Pearl Jam sounds like Creed.
Or am I thinking of the cover to the Doors song? Ack, too many songs.
Edit: To stick to the subject...
Given Pearl Jam's slower tunes, I think they'd sound okay with a slower Creed song. Maybe "Inside Us All" or "Pity For A Dime." Nothing from Creed's
Weathered cd though...
