I know Queen did a lot of overdubbing vocal tracks. I've read some things recently about Brian May also recording multiple guitar parts. I can hear on some tracks that there are multiple guitar parts but my read of some of these articles was that he might also be recording the same guitar part multiple times - like, even the solo's! Does that sound right? I didn't know anyone did this but I can imagine that that would contribute to the rich "violin-like" quality to some of his solo's.
