The Hep Stars performed Cadillac. The performance helped lead to their chart success.

The book Cadillac Madness - The Hep Stars by Dan-Eric Landén & Carl-Magnus Palm says this about this performance:

"On March 23, 1965, five long-haired young men caused a sensation on the Swedish television screens. Running back and forth across the stage, and jumping up and down on the speakers, they performed a song called ‘Cadillac’. After this legendary performance, lead singer Svenne Hedlund became Sweden’s biggest teen idol, and organ player Benny Andersson took the first steps in a career that would later bring him worldwide fame."

This would appear to be Benny's first TV appearance.
