Indie Film Looking For Musical

I am currently producing a no-budget feature-length film in Melbourne. As one of the scenes in the film is set on stage during a musical, I am looking for a musical production with an ensemble cast who would be willing to let us film one of their musical numbers with one of our actors. The scene needs to look like it is an actual performance, so it would be great if we could film a full dress rehearsal. The filming should take no longer than a half an hour, and needs to be done anytime this year. I realise that this is a big ask during the most stressful phase of a production, but if you're interested in being in an indie Australian comedy, please contact me and I'll send you some more details and a synopsis of the film. Thanks, Paul
