Continuing Dikshitar and Semmangudi
My friend Shailesh pointed to this site which has lot of Dikshitar krithis and many of the krithis I had mentioned in my post. Check this out http://sangeethamshare.org /sunil/guruguha/audio/krithis/ He also pointed out that Semmangudi had sung 'Brihadiswaraya' in Sankarabaranam. I have included that in the list. Thanks to Shailesh for his inputs.
