Los chiflados del rock and roll (1957)

Luis, Agustín, Pedro, Ana, and Clara are about to lose their cabaret, "Los bohemios," unless they pay their debt. With a plan to regain funds to pay off the debt, the five friends travel to visit Luis's uncle, Don Apolonio Aguilar. To their astonishment, the uncle refuses to lend them any money, although he is indeed rich. The friends then devise a clever plan to get the money.
