I remember the show and the track well. At the time, I thought the track had something to do with Underworld. Just googled it and discovered it was in fact

Underworld.

Just heard EX track by Mr & Mrs Christmas (no pun etc)called 'Dinner at Rods' which is our hero's voice slowed down with trippy music backin !
