How does that theme song go again?

Alas, the legendary composer Earle Hagen has died Monday at age 88. Surely you remember the folksy television theme song for "The Andy Griffith Show," which he co-wrote and whistled. The Emmy winner ("I Spy," 1968) and Oscar nominee ("Let's Make Love," 1961) also wrote memorable themes for the shows "The Mod Squad," "That Girl" and the "Dick Van Dyke Show."
