 One day, my father was recording the show The Love Boat, which was traveling through the Mediterranean. So he was in hog heaven working with various guitars. One of the violinists in the orchestra called out sarcastically to Tommy. Tommy, do you even know the names of those instruments? He stood up and picked each one up and proudly said, yep, 100%, 50%, 25%, and so on. Here's my father at a seminar in 1983 at Musicians Institute talking about Spanish guitar.
