Rob and Co. I have to say thankyou for the best laugh I've had in a looooong time. My wife and I just spent about an hour just listening to different songs with the pitch bender turned up to about 176%. We just couldn't stop laughing hearing "Alvin" doing all these songs. Other than REM I have to say my favorite song has to be "Blood" by Pearl Jam. I could just see Alvin and the Chipmunks screaming this one at the top of their lungs.
