A Lord of the Rings musical is just not a good idea. They will be singing the elvish songs, so you can't just skip over them.
we have finally caught ourselves flesh and bone
its time for us to feed, but not alone
we will call apon our great lord
but first we must cut you with your own sword
our lord will arise from hell
for the reason is the blood he will smell
because his favorite blood is from a filthy human soul
so come up Amras of Dorthonion out of the hole
