Usher was planning Amy Winehouse duet before her death

London: American singer Usher says he was planning a duet with Amy Winehouse before her death last year. The 33-year-old "Yeah!" hitmaker said that he had approached Winehouse`s producer Salaam Remi for his desire to work with her but could not get enough time to hit the studio with her, reported Contactmusic. "There were a few conversations that took place, but we never quite made to it. I would have loved it. It could have been one of the most incredible records ever. A voice like that comes once in a lifetime," he said. Usher also said that he met Winehouse once and really liked her. "We talked and exchanged information and I invited her to a show and she didn`t come," he added. PTI
