The Merry Monahans (1944)

The film concerns a family vaudeville troupe headed by patriarch Pete Monahan. Because of his love affair with the bottle, Pete manages to get himself and his family blacklisted from every major vaude house in the country. Though Pete's kids Jimmy and Patsy love their dad, they're forced to break away from the act and go off on their own to survive. Eventually, the whole gang is reunited in a shamelessly lachrymose musical finale.
