'We had the good, old days when record companies had money,' says guitarist Ernest Lau. 'We had no time limits or budget constraints. We were so lucky.'

Having gone their separate ways more than a decade ago, the six musicians remained close friends and will reunite this week-end for a 21st-anniversary gig.

All have become leading figures in the local music industry. Lau has set up an audio business, while fellow guitarist Joey Tang is a leading session musician and musical director for the likes of Faye Wong. 'He's the king of the Coliseum,' says frontman Patrick Lui, who is one of the city's most in-demand backing vocalists. Keyboardist Gary Tong is now one of Hong Kong's best known musical directors, bassist Eddie Sing has become a music publisher, and drummer Ricky Chu has set up a music school.

In the early 80s, the young rockers belonged to two bands that united under an auspicious title that came from a prophetic dream by Sing. 'I saw a little star in the sky, and just like a zoom effect I saw that it was the tai chi symbol,' he says. 'The whole idea is harmony, which is important for a band.'

Tai Chi shot to success after winning the first Carlsberg band competition, securing a recording contract and the lifestyle of 80s rockers. For one night only, on Saturday night, fans can pretend the Tai Chi story never came to an end.

The audience can expect a rocking blow-out, as legions of figures from the city's music industry join the band on stage to sing their old repertoire. 'It's going to be a big birthday jam,' says Tang.
