Sweden’s King Carl XVI Gustaf celebrated his 70th birthday on April 30, 2016 with a big royal party in Stockholm featuring an awesome choreographed rendition of ABBA’s “Dancing Queen” by a Swedish army band.

"After a service in the palace chapel attended by the king’s family and royal visitors from Japan, Spain, the Netherlands and Denmark, the outdoor pomp and celebrations for Sweden’s monarch of 43 years included a tightly choreographed military parade. In the palace yard, children gave the king flowers before gun salutes rang out, and he went on a ride through Stockholm in an open horse-drawn carriage."
