Interesting article on the topic when Kolis made their Republic Day debut in 1961:
Their “catchy songs and lively dances became the craze of Delhi”. That’s how the fisherfolk from the Colwad hamlet, in Mumbai’s Bandra neighbourhood, described their reception in the national capital in 1961, where they had been accorded the honour of being the newly formed state of Maharashtra’s first-ever representatives at the Republic Day Parade. So catchy were their tunes, they even got Prime Minister Jawaharlal Nehru to dance with them, a Koli cap on his head.
Fifty six years later, the song that the Colwad Musical and Dramatic Union performed for India’s first prime minister serves as a reminder that it’s impossible to predict how sounds will travel – taking new forms as they float along, inspiring unlikely characters and sparking new endeavours.
