Take That are to make an estimated £75m (€89m) from a 54-date UK tour.
The group announced yesterday that they were reuniting with Robbie Williams - who famously quit the band in 1995 amid rumours of a rift with fellow members Gary Barlow and Jason Orange - and had already recorded an album with him and are now expected to announce plans to play to three million fans next summer, netting a massive £15m (€18m) each.
Take That's last tour 'The Circus' - which Robbie was not a part of - sold out in minutes, but according to insiders, the 54-date extravaganza will be the "biggest show" the band have ever put on.
A source told The Sun newspaper: "Robbie has some commitments with Live Nation and a couple of appearances with Gary for their new single lined up. But after that, Take That's creative tour team will be working on the biggest show they have ever put on.
"Kim Gavin, who has worked with Take That on all their spectacular tours, is already briefed and ready to start coming up with amazing ideas."
It is believed the reformed group - who split in 2006 and announced their reformation, without Robbie, in 2005 - will make a total of £50m (€60m) from the stadium tour, with an extra £25m (€30m) generated from merchandise sales, product endorsements and TV appearances.
A source close to the group - also comprising Mark Owen and Howard Donald - explained: "One sold-out stadium will gross £2m (€2.4m) for the band. Costs will swallow £1m (€1.2m) per show, but after fifty dates the lads will be left with at least £50m (€60m)."
News of the reformation comes shortly after it was revealed Robbie and Gary have teamed up for a duet, 'Shame', which will be released in October.
