Mann in June performed at a concert in Britain where he sang the song which had lines saying that the freedom fighter did not die of wounds inflicted from a cane-charge on him by the British forces in Lahore city (now in Pakistan) in 1928, but due to a heart attack many months later.
"It was not my intention to hurt anyone's feelings. I just sang the lines that were given to me, " Mann said in Mohali.
Rai, popularly known as 'Punjab Kesari' and 'Sher-e-Punjab' (the lion of Punjab), died November 1928, months after receiving injuries from the cane-charge when he and others protested the visit of the Simon Commission sent by the British government to discuss constitutional reforms for India without having any Indian member in it.
