Harry Connick, Jr will appear as a guest mentor and help the Top 5 finalists - Crystal Bowersox, Lee DeWyze, Casey James, Aaron Kelly, and Michael Lynche - prepare for next week with the Songs of Frank Sinatra-themed performance show.

Frank Sinatra, long acclaimed as the world's greatest performer of popular music, is the artist who set the standard for all others to follow. Sinatra was, of course, more than a singer - he was an actor, recording artist, cabaret and concert star, radio and television personality and, on occasion, producer, director and conductor.

A beloved entertainer for six decades, Sinatra's achievements earned him three Oscars, two Golden Globes, 10 personal Grammys (and a total of 21 including those for his albums), an Emmy, a Cecile B. DeMille Award, a Peabody, and he was recognized at the Kennedy Center Honors in 1983. A generous charitable contributor, one of his most prestigious awards was the Jean Hersholt Humanitarian Award from the Academy of Motion Picture Arts and Sciences in 1971. In the United States, Sinatra was also awarded the Presidential Medal Of Honor and the Congressional Gold Medal (Congress's highest civilian award).
