Now, what you hear is not a test - I'm rappin' to the beat, Kangaroo Jack Soundtrack Lyrics Sugarhill Gang - Rapper's Delight Lyrics. I said a hip hop, Hippie to the hippie, The hip, hip a hop, and you don't stop, a rock it To the bang bang boogie, say, up jump the boogie, To the rhythm of the boogie, the beat. Overall, though, Kangaroo Jack is an enjoyable -- if disposable -- soundtrack and a fun musical souvenir for kids who enjoyed the movie.
