I get regular product emails from the good folks at Fender. Among the products in the latest one is the Elvis Kingman acoustic guitar. He apparently played one of the originals in the 1967 movie Clambake. Seeing this I immediately started to wonder what kind of fees Fender is paying to the Presley estate. Obviously they're low enough that Fender is willing to use his name to try to sell this thing, as Fender's acoustic guitars have never been particularly popular.
More that one guitarist has wondered why Fender has never released a Buddy Holly Stratocaster, as Holly was one of the early proponents of the instrument. Supposedly the answer is that Holly's widow wants very high endorsement fees, and is hard to work with.
