Dear Balaji...
"Ennadi Raakkamma pallaakku nelippu"...song from Pattikkaada Pattanama by MSV (not in Engal Thanga Raja).
"Neengal aththanai perum uththamar thaanaa"...song from 'En Magan' by MSV (not in Uththaman).
Both 'Engal Thanga Raja' and 'uththaman' are compossed by KVM only (I am 200% sure).
