no, in the film his voice is mixed with drew seeley (think that's his name) because zac's voice was too low. I assume that's why he wasn't on the tour, his voice wasn't high enough for the songs
probably.
but he sings like, the beginning of breaking free and maybe bits in tho others.
he cant actually sing very wel.
forget the lowness of his voice, he sucks lol
so hes replaced on tour. to save embarrassment =P
Apparently Zac can sing but he didnt have the right voice for High school musical so they dubbed him over with a guy called Drew. The reason Zac isn't on tour is cos it's not him singing!
