I understand your excitement but please be aware that articles like this do appear from time to time. Yanni will be touring in 2013 but when any tour schedule is known and confirmed it will be posted on yanni.com and the social networks. Please keep checking those for any tour information.
I do hope you will have the opportunity of seeing Yanni in concert one day. Yanni loves India and management would love to be able to make this happen as soon as the opportunity arises.
