Can you please welcome me back to Fluther by helping me find this song?

Hello!
I said I’d be a little more active on fluther a while ago, and I’m going to try and stick to that now!
So, to do this I have a burning question that has been driving me up the walls for close on four days now, and at this point I’ve even got cast members from the show I’m stage managing trying to help me (I think it’s starting to bug them too).
WHAT IS THIS SONG?!
Here is a vocaroo that hopefully works of me doing my best to recreate the annoying rhythm. (You’ll finally be graced with my voice to some extent which for some reason sounds like I’m 4 years old (sorry))
I am doing everything possible to not switch keys half-way so enjoy that, no guarantees it’s in the right key at all

Thank you for your speculation and help in advance!!
