This is the place where Stones fans can advertise anything for sale, wanted, trade or whatever, from fan to fan. Advertisements are for free. To see the old ads go here.
What I've heard on a boot was an obvious fan-produced remix like the Bridges to Babylon remix discs. It did not sound professional to my ears. Nico Zentgraf lists it in his bible so who knows...can't imagine a Big Enough single from Virgin at the time although I do love the song.
