A Kanye West show marked the close of South By Southwest 2011 in Austin, Texas at midnight on Saturday night.

And in typical Yeezy fashion, he was joined on stage by a host of famous friends, including Mos Def, Pusha T, Mr Hudson, Kid Cudi and John Legend.

But the guest who got the biggest reaction of the night was Jay-Z who joined Kanye for ‘H.A.M,’ ‘Monster’ and ‘So Appalled’ as well as 'Swagga Like Us’ which went a bit wrong.

“I forgot that one,” Kanye admitted after the song quickly fell apart.
