Hairspray.

I love musicals. Incase you don't know. And I miss being obsessed with this song:

Without Love _ Zac Efron, Amanda Bynes, Elijah Kelley, Nikki Blonsky.

And this is behind the scene of every cast singing the songs:

Includes John Travolta, Queen Latifa, Michelle Pfeiffer, James Marden etc.

BTW, ZAC EFRON LOOKS SO MUCH BETTER SINGING IT LIVE/FOR REAL!! You can soo see the difference in the way how he sings at both vids as well as HSM. You can see how he's faking it on the other one just like you see in HSM (I think he focus more on looking good or something)! YOU HAVE TO AGREE WITH ME ON THIS ONE!!
