No body was expecting much from Yusuf Islam at the 2014 Rock and Roll Hall of Fame induction ceremony. The press had fixated on Nirvana’s reunion and the endless soap opera that is Kiss, mostly overlooking the fact that the former Cat Stevens was about to play his most prominent American gig since quitting music in 1978. After a cheerful acceptance speech that avoided any mention of religion or politics, Yusuf took the stage with an acoustic guitar and delivered a stunning rendition of 1970’s Father and Son that silenced the rowdy crowd at Brooklyn’s Barclays Center.
