god i hope i don't get in a big rivalry with a dopey band!
it ties you forever to another band and create a competition.
being that closely connected to another band is - i think - the worst thing that can happen.
ie: blur/oasis, libertines/babyshambles, foo fighters/nirvana, duran duran/spandau ballet, beatles/stones.
one band will always be in the shadow of the other...
