Similar sounding bands.

Maybe it's just me but doesn't Bono look like Robin Williams?

Yes - Flash

Damned if that Dyson Dc35 vacuum cleaner doesn't look just like a giant pink and silver tone arm.

Beatles-Oasis very obviously;

Alman Brothers -- Greateful Dead -- Steppenwolf -- Doobie Brothers -- ARS -- Kansas -- Don McClean -- Harry Chapin -- Bob Seger and most of the most of the southern rock;

Boston -- John Bon Jovi

Czarivey - Seriously? If I'm reading it right, your last list contains some VERY
strange pairings. Even on the Oasis/Beatles link, seems I've read or heard that
comparison before. Have to say, wasn't following Oasis when they were
"happening" and being raved about. Went back way after the fact to listen to
some of their discography and it was definitely "huh?". Way underwhelming.
Beatles was definitely not something that came to mind. If you will. cite me a
couple of examples where they sound like the Beatles. I'm very curious.
