Okay so I went to a restaurant just last week and heard this kind of Broadway-Like song that is rather catchy.

It goes (man singer):
(something)
step through the fire....
like a bird....
(something)
(and the ending in increasing pitch)
you're a/the swan, you're a/the swan, you're a/the swan!

I'm not very sure if the above is the actual lyrics but they definitely sound like those, thanks for your help! anybody who can point me in the correct direction that will be great.
