[arr] Bolna halke (JBJ) & Azhagana raakshasi

[rayrai2k]

Hi,
Multiple listening of the song Bolna Halke Halke song in Jhoom Barabar
Jhoom made me wonder that this pattern is heard somewhere and just
then realized its Azhagana Raakshasiye (Mudhalvan) or Chidiya tu hoti
to in Nayak. 
Though the vocal portion nowhere resembles, listen to the beats and
the flute + string portion just before the 1st charanam.
somebody who could shed more light to this?
