Hello Rasikas,
This is a request rather than a review of the concert. I hope you all don't mind.
I had the pleasure of attending Bombay Sister's concert at Music Academy on the 26th of December 2008 in the morning slot.  The souvenir book listed their RTP being in Shanmukhapriya.   I am listening  to the concert now and I feel the RTP is in Hemavati.
The play list is: 
1    JayaJayaJaya    Nattai    Jhampa    Purandaradasa
2    Orajoopu    KanadaGowla    Adi    Thyagaraja
3    JananiNinuvina    Ritigowla    Misrachapu    SubbarayaSastry
4    AnandaSagara    Garudadhwani    Adi    Thyagaraja
5    VinayakuniValenu    Madhyamavati    Adi    Thyagaraja
6    Sarasamukhi    Gowdamalhar    Rupakam    MuthiahBhagavatar
7    RagamTanamPallavi    Shanmukhapriya        
8    Kavadichindu    Chenchurutti    Misrachapu    PeriaswamyTooran
I have seen lot of rasikas making a list of krithis sung by the artist.  I am wondering if anyone has made a list of this concert and what ragam was RTP in?
Thanks,
Prasad
