Before "serious" theatre, commercial theatre in Mumbai was the first to explore an Indian idiom in English in the '70s with variety revues that played to packed houses—essentially gags and skits, interspersed with singing and dancing. The first variety revues were directed by Adi Marzban, who also directed Harpo Marx on Broadway.
Marzban then told Dinyar Contractor that if "we have to learn to do Bombay theatre you must learn how to write like we speak". Sylvester Da Cunha, Bharat Dabholkar and Dinyar himself began to write I love Bombay, Bottoms up and Carry on Papa. Bottoms Up's success produced three generations and a genre and language called Hinglish that make "Topical Titillating Tamasha". Grandson of Bottoms Up is the third gen of this Tamasha where the skirts are shorter and the innuendoes less veiled. "I need to make 60,000 per show to break even," says Dinyar and he does.
