Alan Thicke

Alan Thicke (born Alan Willis Jeffery on March 1, 1947) is a Canadian actor and songwriter most recognized for his lead role on the long-running ABC series Growing Pains. He also hosted several game shows, including Animal Crack-Ups (1987-90), Pictionary (1997-98), and GSN's remake All-New 3's A Crowd (1999-2002).

Outside of his acting career, Thicke wrote a great many theme songs, often done with then-wife Gloria Loring, such as those for Diff'rent Strokes and The Facts of Life. He also wrote many game show themes, including The Wizard of Odds (that's him doing the vocals at the beginning), The Joker's Wild (the "Joker's Jive" theme), Celebrity Sweepstakes, and fan-favorite Whew! (although he did not recall doing the music)

Wheel of Fortune
Thicke also composed the 1975-83 music package for Wheel of Fortune, including the show's main theme "Big Wheels" and several shopping/prize cues (among them "Glorious Sax", "Lusherous", "Shavings", "Funky Bridge" {a remix of "Big Wheels"}, "Prize Guitar", and the theme of fellow NBC game Blank Check). Alan also composed the three commercial themes (listed on this wiki as "Big Wheels"; December 4, 1979; and electric-guitar), which got swapped around many times from 1980-83.

On August 9, 1983 the cues made by Thicke were replaced by an entirely new set composed by series creator Merv Griffin (himself no stranger to music). Much like Thicke and Blank Check, one of Griffin's cues was "Frisco Disco" from the 1978-79 revival of Jeopardy!
