I can't get past the many comments mentioning 4-hour gigs. Where does one do a 4-hour gig...???? Or is that being a house band at a tavern where you play all night...? I was only used to short sets at clubs with other bands on the bill. For myself, getting older, stage amplification unloading, setup, and loading (being your own roadie) would be more of an issue on my shoulders and back. (I'm not part of the Cancel Cabinet Culture).
This is a generational thing. In the sixties and seventies four-hour bar gigs were the norm.
