Recently, actor Ayushmann Khurrana has shot with Amitabh Bachchan for his current project on STAR Plus - Aaj Ki Raat Hai Zindagi. On popular demand, the actor-singer sang his famous song, 'Paani Da Rang' along with 'Dard Karaara' from his last movie 'Dum Lagaa Ke Haisha.'

Incidentally, Big B had sent a handwritten letter to Ayushmann for his performance in 'Dum Lagaa Ke Haisha' and Ayushmann confessed "It was a dream come true to receive it (the letter)! I was deeply honored and to be honest, I really believe that a hand-written letter from Mr. Bachchan himself, is better than any award, any day!"

The two actors shook a leg on popular numbers from Big B's golden days and even did the patent Amitabh Bachchan step together. The 'Vicky Donor' actor also recited a poem titled 'Mukhote' which he penned down himself.
