At the beginning I didn't understand what you mean by "It's not easy to define it"
In fact it's a bootleg from Roger's happiness tour in Wolverhampton, Civic center 04.12.94. The last concert of his UK tour.
According to queenonstage, excellent audio recording, so yes, you could share it with us. Furthermore, there's not a lot of Roger's gig here, so it's an occasion to "fix" that and for people here who don't know well, like me, what he did, to get an idea!
