Last week, NPR's Terry Gross asked Memphis blues musician Alvin Youngblood Heart where he learned to play bottleneck guitar, prompting the following dialogue:
HART: [I learned to play] watching Roy Clark on Hee-Haw.
GROSS (incredulous): That's what all the blues musicians say, Hee-Haw. So ...
HART: You learn from the best, right? The main thing was he started playing slide with a jelly jar.
GROSS (Still incredulous): What did you use as your first slide?
HART: A jelly jar.
