Do you enjoy doing Karaoke?
I will occasionally do Karaoke and enjoy it quite a bit. My daughter is quite the opposite in that she prefers to lip synch and perform to the vocal track; maybe we should do an act together, ha.
That might be fun.   Jimmy Fallon does that on his show.
I've never seen that bit (I go to bed rather early). Do The Roots provide the musical portion? I love them. 
Yes, the Roots are from Philadelphia too!
Yeah, the Philly music scene has been really instrumental in American music as a whole and hip-hop in particular. Its an interesting scene.
