Schedule of Carnatic music concerts in Chennai for the month of November 2007 (and other months till January 2008) has been updated at https://ramsabode.wordpress.com/concerts-in-chennai/
More concerts have been included in the December Season Schedule as well (on the same page). Will add the schedules of a few more sabhas when I get some free time in the next few days.
Please refer to this link for directions to the venues (thanks to Bharath for taking pains to put this together)
