MONTREUX - Pop star Lady Gaga and crooner Tony Bennett brought a mix of Cole Porter, Duke Ellington, Frank Sinatra and even Edith Piaf to a sell-out crowd spanning generations at the Montreux Jazz Festival on Tuesday. Legendary producer Quincy Jones introduced the odd American couple, praising Gaga as a singer who had “blown his mind.” Bennett, the only person in the famed Stravinski Auditorium wearing a jacket and tie, and the blond Gaga, appearing first in a long shiny silver dress with plunging neckline, opened with “Anything Goes,” a Cole Porter tune of the 1930s. The pair of New Yorkers then sang “Cheek to Cheek” by Irving Berlin, the title track from their 2014 album of jazz standards for which they won a Grammy Award in February. Bennett, just weeks shy of his 89th birthday, and Gaga, already a six-time Grammy winner at age 29, delivered 30 songs during their 100-minute non-stop show, backed by nine musicians. “We're selling our album around the world, please buy it. She really needs the money,” Bennett quipped. - Reuters
