I've discovered with time, the best concerts are in small theaters right before the band makes it big.
The best seats would be right in front of the sound engineers on the floor, if they had them.
Large stadiums and outside concerts can be fun, but not the best for sound, and after time bands are burned out.
When new songs are learned I try to master them, and when I get tired of playing/hearing them something new is learned.
Sometimes the wife will chime in, please, please, learn something new, you play that over and over and over

I have no idea what songs I knew 5 years ago. Playing the same thing over and over for a long time must be tiresome.
