Natwest Bank ad from the early '90s

[Roxxy]

Does anyone remember an animated advert for the NatWest that came out around '91? It was done in retro-style pen & ink cartoon and was set in a public park, most of whose occupants were normal but a few of them were'nt. It included a guy with a single massive eye, a roller-blading girl buying something from a stall marked 'Bunnies' and manned by a guy with huge rabbit ears, and a gigantic dancing robot. I think it finished when a man is chasing his runaway dog, leaps over a park bench, and discovers that the dog has actually discovered his lost NatWest bank book.

The theme music was extremely punky, with deliberately distorted lyrics that were deliberately warped so that you couldn't understand them. Does anyone know who did that song?? Help appreciated!!
