@Hercule_Poirot = MC is a studio musician. He has hinted he did not cut all ties with being a studio musician. His friend said "You owe me a cover" and he agreed, he's talked about maintaining contacts with the studios, and if worse comes to worse, it's likely he can just jump in his car and camp out a studio for no more than a few days until he gets a session.
A little background.. I know people in bands and I also know a couple studio musicians. Generally speaking, if you're not too picky, there's some work to be had and those jobs don't pay much but it can help cover some bills. But it sounds like he got the good-paying gigs because when you're on the road, those are the ones everyone wants cuz it pays well. So he would probably get a nice gig pretty quickly.. but that's not what he wants. As to the savings, his ex may have spent it or he may have wasted his money going to the parties he's talked about. It could be both reasons, I think.
And I've been in his shoes. I walked away from 2 girls with only my clothes and my car. Both times, the girls started the breakup and it wasn't anything wrong I did. It was issues they were having in their lives that I won't discuss. Anyways, I let them take it all. I didn't want any mementos or any reminders because it hurt to look at it. I needed to move on and I had to. I was okay, in good health, had a car, my clothes and a little cash to find a place (which I did). Really, that's all that matters and interestingly, in both cases, I moved on quicker than she did. In both cases, weeks later, they wanted me back but I had begun to move on...
