From Robbie’s official website:

Tripping was the first single from Robbie’s fastest-selling album, Intensive Care, and peaked at number two on the UK singles chart.

Erroneously described in the press as Robbie Williams' reggae song, ‘Tripping’s' rolling rhythm actually owes a greater debt to the early work of The Clash.

The chorus features a tight-trousered falsetto that climbs the scales like a fireman climbs a ladder, and almost touches disco on its lofty ascent. The first single to be lifted from ‘Intensive Care' and, alongside 2004’s ‘Radio', one of his more idiosyncratic creations.
