About a year ago, maybe less, I attempted to get a classic rock covers band off the ground with a really good guitarist I know. He got several really good musicians involved but when it came to actual practice I found that I lacked the time to actively pursue this project, so I bailed, figuring at that point (2 rehearsals) there would be no substantial loss anyway. Tonight he asked me if I would consider filling in for their bass player early next year, as he will be studying in the US of A (I'm from Belgium - Europe ) and the rest of the band do not feel like putting the band on a 4 month hiatus. On the one hand I am already stoked at the prospect of playing with these people again, and 4 months is a maximum of 16 rehearsals, so I can swing that. But subbing, just for rehearsals??? Idunno, seems like an awful lot of time and trouble for nothing really. And I have my main band for that already So I told him that I would do it on two conditions, the first being that I won't share in the rent of the rehearsal space (hey, I'm not charging them a single thing, and it's a 1 hour drive going there) and the second being that we would actually do one gig with me on bass, even if I have to organize it myself Thoughts and opinions?
