um. oh god. you mentioned alanis morissette. i love you. she's my hero, i adore her. i would seriously KILL to meet her.
well, the dudes from bands i've met, i didn't go and meet. they came and introduced themselves to me. i met two online, one on myspace. then we met up in person which was rad.
but otherwise, the guys from bands i know pretty much came up outside a show and introduced themselves and that's how we met :]
