Van Halens 1980 invasion quickly comes to mind. I knew every word of their every song. They had a new amp system that at the time, a Guinness record for most watts ever at a concert. Couple that with Roth getting drunk, & I couldn't even tell what they were playing.

Hank Jr. Another [bleep] that simply stole my money to just sit in a chair & slobber some chit.

On the other side, Bob Seeger put on concerts good enough that he sold out at Ruckus(Rupp) Arena twice in 6 months.

After getting married the second time & not needing concerts for dates & such I decided my money was much better used for other things & haven't looked back.
