Musical Puns by Collective Cadenza [VIDEO]

I found Collective Cadenza on YouTube when a friend of mine forwarded me the link of one of their videos.  Little did I know that his group of musicians do all kind of musical experiments by mixing and remixing pop songs with orchestral instruments.  You could stuck all day watching all the different videos they have posted.  Thank you recommended videos!

In this video they do a huge variety of songs by a huge variety of bands, but give them names that are puns.  For example:  They do a cover of 'Crossroads' by Bone Thugs N Harmony, but their version is by Trombone Thugs N Harmony and the featured instrument is the trombone.  Get it?

My favorite is probably K-Ci and JoJo or should I say K-Ci and Banjo-Jo.

What is your favorite?
