It is believed that the name of the band, Bhangi, owed its origin to Bhuma Singh, who used to pound bhang (hemp) for preparing a cooling drink for Sikhs gathered at Amritsar during the summer months. Bhuma Singh lost his life fighting against the Mughals led by Diwan Lakhpat Rai in the Chhota Ghallughara in 1746 near Kahnuvan, in Gurdaspur district.
