Rod Stewart at The Colosseum at Caesars Palace
With his 1978 No. 1 single, Rod Stewart famously asked the world "Da Ya Think I'm Sexy?" 100 million record sales later, it's safe to say the world answered "Yes." As one of the top-selling artists of all time, with a career spanning four decades, the Scottish singer-songwriter is one of the most celebrated figures in rock and roll history. The times may have changed, but Stewart's appeal hasn't - with his 28th studio album, 2013's Time, the raspy crooner once again topped the UK Albums Chart - the first time he'd done so since the release of his Greatest Hits Volume 1 in 1979.
