Speaking of bootlegs (were we?) it looks like this brilliant, often-circulated, unofficial recording will finally see the light of day. I remember listening to this killer show--in which Mick Taylor shines--on vinyl back in the mid-seventies, on a bootleg called "Bedspring Symphony." Later, it circulated on CD as "The Brussels Affair," and was highly prized by Stones' fans. Listen to the intertwining guitars of Taylor and Richards, the tight r section of Wyman and Watts, and Jagger's bluesy growl not yet overly campy but seriously in charge. I hope the official release is as clean as the soundboard boots I've heard.
