Stretching the definition of "supergroup"

Meet Chickenfoot, a sort-of-supergroup:

Sammy Hagar recently started a new "supergroup" with ex-VAN HALEN bassist Michael Anthony, guitar virtuoso Joe Satriani and RED HOT CHILI PEPPERS drummer Chad Smith. The band, tentatively called CHICKENFOOT, will enter the studio to begin recording its debut album this summer.

It's not so much supergroup as doing something interesting with leftovers, is it?

Still, Hagar is not without ambition for his bunch of pirate-types:

"We've written eight, nine songs...When people hear the music, it's LED ZEPPELIN. It's as good as that. I know that's a mighty bold statement...We could rival ZEP."

Well, yes, you could, potentially. Or Tin Machine. Maybe you should start by trying to best Tin Machine.
