The American Idol Season 9 Top 5 finalists, who were mentored by actor/musician Harry Connick, Jr., tackled some songs from Frank Sinatra’s musical repertoire in a night dedicated to ‘The Voice’ on Tuesday (May 4). Aaron Kelly dared to sing one of the most iconic and beautiful songs of Sinatra’s songbook, “Fly Me To The Moon” (watch video below).

Aaron delivered a good performance. Randy Jackson and Ellen DeGeneres loved it. But both Kara DioGuardi and Simon Cowell thought Aaron lacked charisma and the confidence necessary to perform such a big song. Simon also said Aaron’s vocals were a bit “corny” and this time, we knew exactly what he meant.
