Boy band Take That fear the ageing process will affect their strenuous dance routines when they hit the stage together next year (06).

The hunky foursome - Gary Barlow, Mark Owen, Jason Orange and HOWARD DONALD - will relive their glory days in major UK stadiums without Robbie Williams.

But now the pop singers are in their late 30s, their fancy moves may be a thing of the past.

Owen says, "I was exhausted just watching the old shows.

"It's going to be tough. I worry my knees will give way."
