Head to the cantina at (384 -1142) in the Mensix Mining Facility on Mustafar and speak with Diskret Stahn. Listen to his story, and he'll teach you to play the Calypso (Song) so he can get the song out of his head. You can also speak with Pey Yi for the Peiyi (Dance) quest. Those who are familiar with LucasArts' Monkey Island series of adventure games may recognize the melody of Calypso as loosely based on the theme songs of the Monkey Island franchise.
