Lojban Song Time

A school "talent show" is coming up and I have determined what I want to do: a Lojban song and (possibly) dance.  I've started messing around with a synthesizer, trying to get the overall sound of the song set in my mind.  Since I only know Lojban grammar (not much vocabulary at all), I require extensive use of a jbovlaste.  It's still very difficult for me to fit the things I'm trying to say into the lines because Lojban doesn't have words like "of", "through", or "with"; those meanings are a part of the sumti.
