The song is narrated by a guy talking about his cousin who doesn't like to dance at all at parties. He's as stiff as a board (hence the name) That is, until one day he sees beautiful Soledad at a party and learns to dance everything from Mambo to Cumbias, just because of her.
The song inspired me to draw Soledad. Sooooo....here she is. Just the way I imagine her :)
