Help me with an ear worm!

[Biblionerd]

What is this chuffing HH song based on? It has been retrying around my head for a week now and I cannot for the life of me work out what the original is!

horriblehistoriestv.wixsite.com/horriblehistoriestv/song-i-can-t-go-on

I don't think it is, it's listed here as just pop music

That'll be why I've not found it by googling then!
