Deemed "possibly the most exciting engagement of my professional life" by the Chairman himself, the Vegas gig heard on Sinatra's first live album was recorded when the singer was a feisty 50. He's in particularly high spirits, bantering with the audience and unspooling a long "Tea Time" monologue that Rat Pack buffs will relish. Hear Sinatra recapture his wayward crown and deliver definitive versions of too many tunes to mention while a young Quincy Jones conducts the mighty Count Basie Orchestra through his own electrifying arrangements.
