When Convention Centre boss Cliff Wallace sits down among the 8,000-strong audience to watch the Rolling Stones in Hong Kong later this month it will be in markedly different circumstances to his last Stones gig. About 20 years ago he was in charge when, at the height of their popularity, Mick Jagger and the boys played their biggest concert before a 87,500 crowd at the Louisiana Superdome in New Orleans. That was 1981, during what was supposed to be the last tour by the dinosaurs of rock. 'It was the most memorable concert I have done, in terms of everything we did,' Mr Wallace said. 'I can tell you I was real nervous. Yes, from 87,500 to 8,000, it's quite a difference.' He says the Hong Kong concert will be just as difficult, despite the lower attendance. 'The Stones concert is going to be more demanding than any concert we've had simply because of the requirements,' Mr Wallace said. 'They are going to have more security requirements than any show we've had. It's taking an awful lot of time. 'It will also be the first time we will use our new telescopic riser seating system in the back of Hall Three.' It will also be the first time he has seen the band since the 1981 show, and time to renew an old acquaintance with Jagger. 'I talked to Jagger that night, well it was more of a confrontation really,' he said. 'He confronted me because we were selling dacquiris and he found out about it. The rule was no alcohol. Now, in New Orleans, a dacquiri is not considered alcohol, it's considered a fairly woosie drink - so I went in and had a little argument with him. In the end we sold dacquiris.' The Rolling Stones put in place a strict no-alcohol rule at all their concerts after their 1969 Gimme Shelter Tour. The Hell's Angels were hired as security for that tour and at an infamous concert in Altamont, Illinois, a fan died in an attack by a Hell's Angel.
