Sir Elton John, one of the most acclaimed artists in all of pop history, announced he was retiring from performing live more than a year ago. We weren't sure if it was really true because he's still going strong and could carry on for years to come if he wanted to. But just in case he means business, pay attention to this: John's 'Farewell Yellow Brick Road' tour includes two consecutive dates in Barcelona's Palau Sant Jordi. From his debut in 1969, John has sold millions of albums, and you won't want to miss the chance to hear him performing huge hits that have thrived over 50 years of the artist's career, including 'Rocket Man', 'Tiny Dancer', 'Your Song', 'Don't Go Breaking My Heart', and 'Candle in the Wind', which has sold 33 million copies around the world, second of all time only to Bing Crosby's 'White Christmas'. John has played more than 4,000 concerts in over 80 countries, don't miss out on some of his final performances.
