You have had practice sessions. Is it unusual to go for an hour and a half without a break in a practice? The entire practice was 2-1/2 hours. My real gripe is that there wasn't a place for me to sit down. I stood the whole practice session until the last song when I finally got a bench to sit on. We're supposed to play our gig on Saturday, so I'm not uncomfortable with spending the time, it's just too concentrated and I don't get much chance to fool around with the bass lines to improve what I have. I'm beat and weary, have to go to work, then go to practice and we do each song once, twice at the most. And the set ballooned from 7 songs to 15, so I expect an even longer practice tomorrow. I haven't practiced like this in 25 years. Back then we worked on one song until we had it down. It might take time, but the band would work on bits and pieces until it gelled into something we were all happy with.
