I think hardcore fans sing along no matter what. (When I saw Paul, I would not STFU pretty much the entire time, not sure how much everyone else hated me, LOL.) But for certain songs, I think Ringo will ask the crowd to join in, you see. I definitely sang along with Ringo, though!! But for me, I was so happy to see Ringo that I didn't care if people messed up the words or sang badly. And yeah, for me and the hubby, opposites really do attract.
LOL, does Ringo know he's your husband? Barbara might have something to say about that! Over at the "You know you're a Beatles fan" thread, I was ranting about people not knowing correct facts about the Beatles...ahhhh, so annoying.
About saving...I'm okay with saving money, but certain things (cough concerts cough) are GREAT motivators. You said you've been wanting to travel so this is a good start!!
