You may not know his name, but you know his music. Hoyt Curtin was a composer extremely active in the 1960’s and 70’s where he worked for Hanna Barbara composing most of their theme songs and show music. Back in the 60’s he was only listed as “Music Director” but today he deserves his place as composer of such classics as The Flintstones, Jetsons, and Scooby Doo.
