I learned this ar­range­ment from the sound­track CD, which ap­pears to be a lit­tle dif­fer­ent than the ver­sion most of the peo­ple play­ing this up­load­ed to youtube. I don't know if that's the ver­sion they used on "Fam­i­ly Guy", be­cause I nev­er saw that episode. (I'm old enough to re­mem­ber the mu­sic from watch­ing the Hulk when it first aired.) Com­posed by Joe Har­nell. It's one of my fa­vorites.
