8 p.m., Alltel Arena. $49.50-$79.50.
Say it with me: “Boo-blay.” Two years after his first appearance at Alltel, the Canadian crooner returns on Saturday bolstered by a firmly established international stardom. For those of you who don't follow Canadian pop music, or who didn't catch Buble on “American Idol” or “X Factor” last year, or who haven't heard his interpretation of standards on commercials for Starbucks and ESPN poker, the vocalist is a throwback, an adherent of the jazz/swing era who recalls crooners like the Mills Brothers and Sinatra. Like his forebears, Buble wraps his silky, smooth voice around standards and contemporary pop alike. On his latest album, “Call Me Irresponsible,” he covers “I've Got You Under My Skin” along with Willie Nelson's “Always on My Mind” and Clapton's “Wonderful Tonight” (interpreted here as a bossa nova). Look out for swooning ladies of all ages.
