I like “When Sparks Fly”.
The theme music can be Prince’s song, “When Dove Cry”, or a portion thereof. If I recall correctly the song begins with a engine revving. I believe it is a motor cycle engine, but an engine just the same. I think it would be perfect!
Can’t wait to see the show. I will definitely swoon in, along with all of the other buzzards.
