"O Mor Romjaner Oi Rojar Sheshe Elo Khushir Eid" is a Nazrul Sangeet, Written and Composed By Bangladesh's National Poet Kazi Nazrul Islam. This song becomes very popular at the time of Eid-ul Fitr. Because, after a month of fasting Eid-ul Fitr comes, and the meaning of the first line of this song is that.
Hope you'll enjoy the Instrumental version with Melodion & Guitar played & recorded by Kh. Koushik Ahmed Antar at Heart's Rhythm Studio.
