Funny story about that theme song . . . my family and I were in Key West. We just finished dinner and my brother and I wanted dessert but we didn't like anything on the restaurant's menu. We decided we wanted ice cream instead and there was an ice cream store across the street and and a couple stores down from the restaurant.
On our way there we had to pass in front of a gay club. Blasting out of the doors and windows was a dance remix of the Speed Racer theme song!
I always suspected he was gay. Always hung with Sparky, never kissed Trixie.
