American superstar singer Alicia Keys thrilled a packed Manchester Cathedral with a special one-off gig. And it seems the venue left just as big an impression on the R&B musician."This place is beautiful. Suddenly my show got much better," she declared to an audience of competition winners and VIPs, which included football stars Joe Hart, David Silva and Robin Van Persie."I love the UK," she added. "You have such amazing people. Such amazing ideas. And a lot of sarcasm!"Keys was note perfect throughout as she belted out her hits including "No One", "Fallin'", "If I Ain't Got You" and "Empire State of Mind", changing the main lyric of the latter from New York to Manchester to the delight of the crowd.The event was being filmed for a special edition of 'MTV Crashes' due to air on October 28th.
