Disco happens to be one of my favourite kinds of music. It's the perfect rithm to dance to, in my opinion. My dad used to be a Dj during the golden era of private radio here during the late 70s and trough all the 80s. We have the original double lp from Saturday Night Fever (altough now it's broken, wore out from too much plays, shame..) among his vast lp collection. We didn't have this record, but when I first heard it some years ago I immediately fell in love with it. Star Wars came out when disco music was all the rage, so it should be natural that the two things would marry so well.

I really like how he played with all the different themes. One of my favourite renditions (if not THE favourite) is the Cantina theme. I could listen to that part all day.
