As per the Nalli’s Chennai Music Season Reckoner for 2013-14 (S Kannan and Not for Sale), Nagai Sriram’s schedule for 22nd is as follows:
5.00 PM – Kartik Fine Arts – accompanying TNS Krishna
6.15 PM – Kalarasana – accompanying Sanjay Subrahmanyan
6.45 PM – Charsur Fine Arts – accompanying V Sankaranarayanan
In this e-age, anything is possible but given Chennai’s traffic, he has to be an e to negotiate the distances.
This by the way is a Season Fact and not a Season Vumb.
