Pharrell Williams and Maroon 5 will perform as music stars at the Sinapur Grand Prix. The multiple award winners will perform in front of a crowd on Singapore’s largest entertainment stage. On the smaller stage, spectators will be entertained by the Spandau Ballet, one of the most influential bands from the UK. Williams' performance, which most people know from the single Happy, will follow Friday's events on the track, ie. September 18th. The other two groups will sing their pieces after Saturday's qualifying round. Access to the stage will be provided to three-day ticket holders, and other details will be announced by the organizers in the coming months. The race in Singapore itself will take place between 19 and 21 September.
