Top 3:
"Heroes" - cut from Wonderland after Tampa (can be heard on the cast recording though)
"Finding Wonderland"
"Lovesick" - Women/verge
From the songs that I have heard, "Go Back Home" from Scottsboro boys.
I haven't seen "Catch me if you can", but "Fly Fly Away" has been out there on the youtubes for about five years, so I guess that counts as a close second.
HASA DIGA EEBOWAI from that show about the Mormons.
