Holy Rock N Roll, Batman! Robin has a record, the vinyl kind. Trying to capitalize on the popularity of TV’s dynamic duo, M-G-M gave Burt Ward (Robin) a recording contract. But neither the Joker or the Riddler could make it a hit. The song, “Boy Wonder I Love You,” was written by Frank Zappa, which certainly adds to its value. A store-bought copy is worth up to $75.00. A promo or DJ copy, as shown here, is up to $150.00.  To find the value for all promo copies, click on “Mighty John’s Promo Records Guide” in the yellow strip above.
