Is it normal to be charged a bond in amateur musicals?

150k to stage Chess? Must be a hell of a show the director has lined up. I totally disagree with asking people who commit their time, talents and effort into a show to pay that amount of money. Does everyone else involved in the show have to pay the bond as well or is it just the cast? As an MD of amateur musicals where the musicians don't get paid (and neither do I), if I were to ask my band members to pay me to ensure they showed up, I can guarantee you I would never be able to get a band together. If it's just the principals that are the problem, maybe the director should use some of that 150k to pay them a fee and ask them to sign a contract. If you want to stage a production that big, then its up to you to pay for it; not the cast.
