Jagger taped a little stick to his upper lip (a mustache) and was singing that Italian song, "Figero, Figero..." (However you spell that!). The hilarious part is that he was singing, "PIGero, Pigero..."
Jammin' Jack!!! He has become absolutely obsessed with music...actually, as he says, "Wock-e-Woe guys". He is constantly playing his guitar (as you see here), his drums, singing in his microphone (mah-pone), and even closes his eyes and nods his head when he's really "into" the music! He is something else!!
This was a funny sight. Jagger looked like Fred Flinstone, and Jack thought he was so big to be pushing his brother!
