WATCH: ELTON JOHN Rocks The First Night Of Apple Music Festival!

Opening Apple Music Festival 2016, Elton John gave his audience an unforgettable show at The Roundhouse in Camden, London.

The Rocket Man brought his old tunes back while integrating re-workings of his glorious songs. Setting the tune of the night, he opened with "The Bitch Is Back", "Philadelphia Freedom" and "I Guess That's Why They Call It The Blues" which were well-applauded by the crowd.

The 69-year old singer promised that it will be "a night of surprises" as he invited undiscovered musicians he found through Apple Music Radio to perform with him onstage. Among his guests were Rosie Lowe, Gallant, and folk singer Parker Millsap who performed classics like "Don't Let The Sun Go Down On Me" and "Tiny Dancer".

Now on its 10th year, the annual festival hosted by Apple is offering 10 days of "exhilarating nights of live music" from September 18 to 30. Here's the lineup of artists who will play in The Roundhouse: The 1975 and Christine and the Queens, Alicia Keys and Jordan Fisher, OneRepublic, Calvin Harris, Robbie Willians, Bastille, Britney Spears, Michael Buble, and Chance the Rapper.
