There's an indelible Holi tracklist that surfaces every spring and goes back into the annals of forgotten history within a span of 24 hours. It resurfaces every year, but never manages to last beyond a day or two. This list features such classics like Rang Barse from Silsila featuring Amitabh Bachchan and Rekha, Holi Ke Din Dil Khil Jate Hain from Sholay featuring Dharmendra, Hema Malini and Aaj Na Chodenge from Kati Patang featuring Rajesh Khanna and Asha Parekh.
