Do you remember this US number one single from 1974/75?
It seems it's back in the charts again. It's used in a trailer apparently, although I haven't heard it.
It's a good job they didn't use the Jonathon King version.
Yep, catchy song. One of four Swedish artists to have an american number one(or at least there were 4 when I gave up pop quizzes a couple of years ago)
