His first was to tell the show's makers that none of the contestants should dance to any song picturised on him and ex-girlfriend Aishwarya Rai. His second demand: to exclude any Shah Rukh Khan songs! Child contestant Darsheel Safary and his partner danced to a song from SRK's 'Dilwale Dulhaniya Le Jayenge', and Salman came on the show only once the performance was through!
Since Madhuri Dixit is one of the judges on the show the audience wanted to see Salman dance with her but he was reluctant to. It was only after much persuasion from Katrina Kaif (who was also present) that Salman relented.
The buzz is that Katrina got a bit of a mouthful for insisting that he dance with Madhuri. Apparently Salman ticked her off while they were exiting the show and on the way to their van.
