Lovebird, that's partially true and confirms what Jay Scorpion wrote above!

Celine's "A New Day.." Casino Stay did $390 milions during more than 5 years (2003 - 2007) and 700 concerts with a 3 million people audience and 70% of the concerts sold out. During this "tour" Celine did more concerts than Madonna all tours combined during her 32 years in business !!! But as it's a one venue tour it isn't considered a propel tour.

Celine did better in 2008/2009 with "Taking Chances Tour" 132 concerts that grossed 270$ millions in only 1 year. Even though it's good it did 2.05 million per concert.

Madonna's "Sticky and Sweet" tour was during 1 year (23 August 2008 to 02 September 2009) and did 408$ millions with only 85 concerts for 3.5 million fans (100% concerts sold out). After she did concerts during 4 months in 2008 she got to $282 millions and was already the #01 tour for a solo artist and the best grossing tour for 2008. The concerts during 2009 were a second leg doing some of the locations again and a few new cities during 2 months (04 July to 02 September) made it the #02 tour for the decade. She was able to do $4.8 millions per concert on average!

And Madonna's "MDNA" tour did $305 milions in 6 months and a few days with 88 concerts, and 100% of the concerts were sold out. She still managed to do $3.5 millions per concert. Of course it was the best grossing tour for 2012.

Got the picture now? Even Celine Dion doesn't come close. Beyonce is doing $1.8 million on average from her current tour so not that far from Celine numbers. If she can put on a few more dates she will pass Celine Tour with ease... but to pass Madonna she will need to do at least 230 concerts grossing that kind of money on average.
