 Dog... #AlanThicke just wasn't the cool dad on tv. Dude was a part of our everyday musical lexicon. As a songwriter and jingle man this dude was THE MAN. we live in an age in which most tv shows eschew the art of the theme song. Most of our shows are quickie tags or nothing at all. Or instrumentals. Next to #JesseFrederick & #MervGriffin You were employing Alan to handle the honors. As a dude working in television believe you me: the art of connecting melody and narrative and sticking in 30 secs or less is an ART (I still maintain the #FreshPrince theme is Will's best most loved song (yes, more than #Summertime)---Alan had classics that NEVER LEFT us: #DiffrentStrokes theme #FactsOfLife theme my Uncle Bud used to laugh at me trying to whistle the #JokersWild theme (game shows were waaaaay big in the 70s yall and Alan did em all including the OG version of #WheelOfFortune back when Woolery was host) I mean 2016 is what it's going to be. I just hope I love to escape it. Respect to his family and his loved ones.
