RR, I don't think there's M2 in the TMS portions (or for that matter anywhere else in the song, but will check again). While LRE's portions has an anya swaram in Ni2 (IIRC) in the 1st charanam (eg. kaadhali), TMS' portion seems to be fully in Sivaranjani (ofcourse, I'm not considering the last charanam which has lot of syncopation notes where he tries to incorporate rocknroll style). That slide from keezh Sa to mEl Sa and spiral descend through the Sivaranjani avaro (ulaginil aanavar aayiram aayiram)... just love that!

scale shifting (esp placing the shadjam)... orE kashtamappa!
