Another vote for Mr Brownstone from me.
I remember the anticipation for use your illusion being immense (at least from me) and it was all just a bit disappointing wasn't it? I got a bootleg cassette from a record fair around 1990 which had a load of demos on, some appetite ones and some which subsequently appeared on illusion. There was a great version of November rain with just a solo piano which leaves me with a soft spot for that song, even though the illusion version is obviously preposterous.
I read a thread on here recently suggesting how illusion could be a great single album with some decent quality control which got it just about spot on.
