I've written eight Marvel Comic songs -- The Silver Surfer, Captain America, The Hulk, Doctor Doom, Thor, The Thing, Doctor Strange and The Watcher.
My original plan was to do a rock opera with the musicians performing in the character of the heroes and villains, with multiple voice. But shortly after writing these songs I got involved with elected politics and they ended up on the back burner. In fact, they're still on the back burner--lol!
Anyway, here are four of the ones I managed to get recorded:
The Silver Surfer -- Performed Solo
Captain American -- Performed by The Rolling Beatles
The Hulk -- Performed Solo
Doctor Doom -- Performed Solo
