Alan was not only a celebrated actor, but also an accomplished musician. The Ontario native created the original theme song for Wheel of Fortune, as well as the lead tunes for Facts of Life and Diff'rent Strokes.

Gloria Loring, Robin's mother and Alan's first wife, also took to social media, thanking friends for their support via Facebook.
