The group's first number one was the hit 'Pray' in 1993. Take Thatsplit upthree years later but not before they hadamasseda hugefan base, sold more than 15 million records andscoredeight number one hits.

Robbie Williams went on to become even more successful as asolo artistafter he left the band but, for the others, their days as Take That members continued to be their mainclaim to fame.

Today, Take That joins a growing number of bands who havere-formedor who arere-releasingprevious hits. Inthe album chartsthis week, Irish boy band Westlifefended off competitionfrom Oasis, U2 and the Beatles to take the top slot with The Love Album. All four of these bands have been together (or in the case of the Beatles were together) for many years. In fact, together, these bands have been making music for almost 50 years.

He continues to sing the same songs that he's sung for more than 20 years because, he says, "it's like swimming underwater, it's like diving. You know total freedom. Theoutlet, the emotionaloutletwhen you're singing is the most wonderful feeling."
