Winehouse had not been given a deadline to complete her third album, for which she was learning to play drums. In May 2009, Winehouse returned to performing at a jazz festival in Saint Lucia amid torrential downpours and technical difficulties. During her set, it was reported she was unsteady on her feet and had trouble remembering lyrics. She apologised to the crowd for being "bored" and ended the set in the middle of a song. During her stay in Saint Lucia, however, she worked on new music with Remi. On 23 August that year Winehouse sang with the Specials at the V Festival, on their songs "You're Wondering Now" and "Ghost Town". Island claimed that a new album would be due for release in 2010. Island co-president Darcus Beese said, "I've heard a couple of song demos that have absolutely floored me." In July 2010, Winehouse was quoted as saying her next album would be released no later than January 2011, saying "It's going to be very much the same as my second album, where there's a lot of jukebox stuff and songs that are... just jukebox, really." Ronson, however, said at that time that he had not started to record the album. She performed "Valerie" with Ronson at a movie premiere but forgot some of the song's lyrics. In October, Winehouse performed a four-song set to promote her fashion line. In December 2010, she played a 40-minute concert at a Russian oligarch's party in Moscow, with the tycoon hand-selecting the songs. In January 2011, Winehouse played five dates in Brazil, with opening acts of Janelle Monáe and Mayer Hawthorne. The following month she cut a performance in Dubai short following booing from the audience. Winehouse was reported to be tired, distracted and "tipsy" during the performance. On 18 June 2011, Winehouse started her twelve-leg European tour in Belgrade. Local media described her performance as a scandal and disaster; she was booed off the stage due to her apparently being too drunk to perform. Serbian defence minister Dragan Šutanovac called Winehouse's performances "a huge shame and a disappointment". It was reported that she was unable to remember the city she was in, the lyrics of her songs or the names of the members of her band. The local press also claimed that Winehouse was forced to perform by her bodyguards, who did not allow her to leave the stage when
