Queen as progressive band?

It's the overdubbing..... they did sh*t loads of it, probably more than any other band in the world. Queen II is just drenched in thick vocal harmonies that sound like 100+ vocalists, they're splattered everywhere, in all corners of that album. And this continues into songs like Somebody to Love, Bicycle Race, and of course, Bohemian Rhapsody.

It's not to everyone's taste, but it was certainly progressive (particularly if you listen in quadrophonic.... it's like having four choirs screaming at you from different directions, in a good way!)

 I was thinking about Queen since yesterday was Freddie Mercury's Bday and was wondering what was the general consensus among prog enthusiasts regarding Queen? I for one have always been a pretty big fan of Queen especially their early material from their self titled debut album right on up to The Game and even some of the later pop hits on Its a Kind of Magic, Innuendo, The Miracle etc. My argument would be their lyricism obviously especially on Queen and Queen II dealing with many of the same themes as some of their contemporary Prog acts ie: fantasy, romanticism etc...Their groundbreaking use of intensely over-dubbed choruses and whatnot also was progressive in its use of studio technology much in the same way other groups were stretching the recording process and pushing the bounds of the technology of the day. And of course the stunning musicianship of Brian May, thunderous drumming of Roger Taylor, the quiet dependable and precise playing of John Deacon (one of the great underappreciated bassists IMO), and the sheer magnetic stage presence of Freddie Mercury arguably one of the greatest singers and performers of all time. I understand their commercial success and radio hit leanings might be a turnoff for many of you so I was curious as to everyones thoughts. I absolutely adore them to be honest. How about you?
