We do love a large chunk of cheddar with our Christmas tunes here at HuffPost Celeb - but we think we've almost reached our cheese limit after listening to John Travolta and Olivia Newton John's Yuletide offering.

The stars have reunited 34 years after starring together in 'Grease' to record a whole album of festive songs in the name of charity and well, not to be too uncharitable, but they've made possibly one of the oddest videos of all time for the first release, 'I Think You Might Like It' (ahem).

Our Top 5 fave bits...

1. John Travolta's hair
2. John Travolta singing behind the wheel (of his plane)
3. John Travolta singing behind the wheel (of a gift-filled cadillac)
4. The 'Especially For You'-style reuinion
5. The line dancing

Like we said, odd. But also amazing.

Travolta and Newton-John will donate the artist proceeds from the album equally to their respective charities, the Jett Travolta Foundation and the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia.
