The very start makes me think of Series 5 and Smirkenorff flights.

Paul Simon - You Can Call Me Al

Elf portal at the back (once the door's open).

Phil Collins - In The Air Tonight

The corridor at 2:41 reminds me of the Series 3 dwarf tunnels. (Also, as a reference to another CITV series, in the lead-up to 3:15 try saying, "This is an art attack... this is an art attack... This is Art Attack!")

*"If everything stops for time out, why don't I stop for time out?"

"I'm working on it, madam. Believe me, I'm working on it!"* - Majida and Treguard, Series 8

"Just you shut your mouth" - David Bowie, China Girl

Puppy - Arabella
