Yeah, that would be "chukkalu themmannA thetn)chukku rAnA". UObscure tidbit; april okkatti vidudhala was remade in tamil with (murali?)-shobana as Sathiya Vakku which has a tamil version of chukkallu themmannA, which makes it another song in tamil with same tune as chitira sevvaanam. A bit like thumbi vaa though not at the same scale as thumbi vaa reincarnations. One more tidbit: april okkatti also has a reworked version of Chinna mani kuyilae currently in focus in app engine's SPB-IR series - the lyrics go "chalti ka naam gaadi". I believe that also has a tamil version in sathiya vaakku
