Hello arvinderrathore,
As a born and bred tru-blue Punjabi jatti very fond of old Punjabi songs, and also a professional writer of caliber, I can write Punjabi lyrics for you in roman script. Here is an example:
Hun watnan nu chal sonya, din dubya, raat hoyi, gal mukki te rolle vi chupchan hoye.....Othe chal hun jithe haale wi loki teri yaad ch ne ronde paye.....chhad beganyan nu, tur apne des wal, othe ne deeve blade hoye...
I can write lyrics as poetry, not on tunes. Please get in touch if interested.
Regards
Namita Jain
