Yeah, there are only so many chord progressions, but those two are extremely similar, I'd lean more to a rewrite than coincidence, but I guess the Finn is the only one who knows for sure.
It's either the club CD Mood Swinging Men or Eyes of the World where Neil says he rewrote Four Seasons as Catherine Wheels. Remember it's only the chorus that was demoed during the Frenzy rehearsals in 1978, just before someone points out that Catherine Wheels predates Four Seasons
