Someone Else's Favorite Band

[Clodfobble]

My mind wandered last night to the surprising number of big concerts I've attended because they were someone else's favorite and I was obliged to tag along. In chronological order:

Foo Fighters
George Strait
Pet Shop Boys
Legendary Pink Dots

In addition, I saw Sugar Ray only because a friend and I loved the band that was opening for them, and she convinced me the 20 minute set would still be worth the bigger band's ticket price.

Do other people do this a lot, or is it an indicator of how much I subsumed my own personality in my youthful relationships? As far as tickets I've bought for myself, it's been musical theatre or stand up comedy almost every time.
