So Ayu went to Madonna's concert....
I bet you that in Ayu's next arena tour, she'll have borrowed some elements from Madonna! Everyone watch Madonna's Confessions Tour on NBC this November... then we can compare it to Ayu's next tour ;-)
They've already done so many similar things: coming out of big globes at the beginning of the concert, hanging on crosses, doing the whole brit-punk/kilt thing...
If Ayu has any equestrian or disco themes next time, we'll know where she got her inspiration
