How often should I do a tune up?

In the 50s version, all the tunes played here were selected by home viewers. Each correct tune won money for the winning contestant as well as the home viewers. The first correct answer was worth $25 and every subsequent correct answer doubles the money. Naming all seven won $1600 and gave a home viewer a chance to come to the New York studio where the show was taped at that time, and play along with the studio contestant in a special round called the "Golden Medley Marathon".
