Bono made a surprise appearance on Sunday night at Bemelmans Bar at the Carlyle Hotel in New York, where he joined singer Jim Caruso and pianist Billy Stritch onstage for a handful of standards, the Huffington Post reports.

"Bono walked in. It was impossible not to recognize the guy – the glasses alone gave him away!” Caruso recalled to the Post. "They were seated in the corner, where they rocked, bopped, swayed and snapped. He kept giving me the thumbs-up when he'd like a tune and singing along quietly."

Stritch and Caruso were performing tunes from the Great American Songbook, a set of classic songs that the U2 frontman knows well. Before Bono left, he headed right for the stage and joined in harmonies to "I've Got You Under My Skin," a track he recorded with Frank Sinatra in 1993.

"The room was stopped cold," Caruso said. "Just another miraculous Bemelmans moment! After the last note was crooned, Bono flew out the door, waving to everyone. Billy looked at me and said dryly, 'Well ... that happened!'"

Taylor Swift is music's queen of moneymaking, according to Billboard.

Taylor Swift doesn't wrap up her "Speak Now" World Tour until August, but the pop-country singer and six-time Grammy winner can celebrate with her team a little early: Swift topped the Billboard Top 40 Money Makers list of 2012, earning a reported $35,719,902 in 2011.

In 2010, Swift probably thought she had hit her peak with her award-winning "Fearless" album and subsequent tour. But the superstar couldn't stop writing. Swift released her third studio album, "Speak Now," in October 2010 and was an instant smash; the album sold approximately 1,047,000 units in its first week. The record catapulted Swift into her accompanying tour, and grossed $88.5 million in the U.S. alone, according to Billboard. As of 2012, the album has been certified quadruple platinum by the RIAA, selling 4,005,000 copies in the U.S.

Swift netted a staggering $29.8 million from her tour in 2011, according to Billboard, but perhaps what really launched her to the top of the Money Makers list is her songwriting abilities. Because Swift wrote all 14 songs on "Speak Now," her income benefited with songwriting royalties.
