"konjum malar manjam" - what a great song!!! But sandham is similar to an IR song
"vaanam niram maarum" [But the ragas are different] from DhavaniKanavugal which got released few years before Janani.
Also MSV has reused the same phrase from his late 70's VJ solo song "Ganga Yamuna saraswathi" [ I don't know the film name]
for the line "vaarayo yen uyire" .
BTW, there is a song "welcome you are welcome" . Can anybody tell the movie and the MD for this song? I think SPB has sung this song.
