Was Rory Gallagher gay

Answer 1

No, he wasn't.

He had a long-term girlfriend - an American.

His reason for not marrying was that he felt any sort of family life would be incompatible with a life touring the world - and he said this on a few occasions.

Answer 2

It's hearsay so you can take it with a pinch of salt if you want but a friend of mine in the music business who would have been the same age said he was.
