I agree, it's all about waiting around to find out. It's never a sure thing. Who knows what commitments Neil may have after each gig. he may need to hit the road right away, he may be tired and ready for bed.
I don't always wait around. it depends on who I'm with and how far I have to drive to get home. However, the couple times I have waited around, I've never been disappointed. Back in 2005 I got to meet both Neil and Tim and have them sign my Finn scrapbook!
