Tips, Tricks and Tools To Help You Sing!

We are planning to stage a musical Fiddler on the Roof. How will live playback singing work?

Of course, there will be a small live band accompanying. But instead of actors singing themselves, will this idea of live playback work? Has anyone tried this before in a musical play?

Either cast actors who can sing live, or do a non-musical play. Please don't have the actors lip-sync, that sounds awful.
