I have attempted a beautiful Sabad Kirtan, comprising of couplets composed by Shri Guru Nanak ji in the 15th century. This traditional Bhajan/Kirtan was featured in Hindi film 'Halla Bol' (2008), sung by Sukhvinder Singh. The couplets, set to the traditional lilting melody of popular North Indian devotional kirtans, are composed in an amalgam of mediaeval, colloquial dialects and nascent veranaculars of North and West India such as Awadhi, Brajbhasha, early Punjabi, Sindhi, Rajasthani, other 'Apabhramsha' (popular spoken simplified forms of Sanskrit) and Arabic. They were thus composed in the language of the common people of that time, as was the practice of the Bhakti saints of the period. The words testify to the deeply mystic spirituality of Guru Nanak. They stress the crucial importance of the 'Satnam' (True Name of the formless God), 'Satguru' (True Guru) and of loving devotion to both of these in order to attain the Divine.
