A challenge many of us in the performing arts have is getting people to come see our shows. Believe me, I have had plenty of instances where I tell dozens of people about a comedy show, some of them tell me they are definitely going, and then NOBODY shows up. It's really disappointing.
Over a year ago, I posted an article titled "2 Great Ways to Get Lots of People to Your Comedy Shows". One of the ways I suggested is to join Meetup.com, join meetups that interest you, and then tell other people in the group about it.
Recently, I joined a singles group, and went to a couple of their activities. I saw a good movie with them, and then later that week I took salsa dance lessons with the group. I told the others that I do stand up comedy. The organizer of the group asked me when my next show was, and I told him. He was gracious enough to put my show information in one of the next singles meetups. Lo and behold, lots of people from the meetup showed up, and the venue was packed!!!
So if you have a show where you need to have an audience, go out and make some new friends!
