American Idol’s five finalists are singing songs made famous by the original kings of cool– Frank Sinatra, Dean Martin, Sammy Davis, Jr., Peter Lawford and Joey Bishop—collectively known as the Rat Pack.

Kris Allen sings The Way You Look Tonight. Great pick. Surprise mentor Jamie Foxx says he’d do a record with him right now.

Randy: “This is your best performance to date.”

Kara: “You have set the technical standard so incredibly high for this evening…you are truly a dark horse.”

Paula: “You’re now a sophisticated gentleman…the performance was near impeccable.”

Simon: “I thought it was a little bit wet.”

We will upload the video of Kris’ performance later. Meantime, check out this clip from the 1936 film Swing Time.  The song was sung by John “Lucky” Garnett (played by Fred Astaire) while sitting at the piano.

Here’s the video of Kris Allen signing “The Way You Look Tonight” on American Idol (April 28).
