[arr] "Udal_Mannukku_Uyir" & "Unnodu_Nan_Irundha" in Iruvar????

[V S Rawat]

What exactly are Iruvar's "Udal_Mannukku_Uyir" & "Unnodu_Nan_Irundha"? 
Not songs by any stretch of the word. Some recitation or just dialogs?

What was happening on screen?

ARR's albums normally don't have dialogs.

TIA.
