Queen Elizabeth has become the second English monarch to reach 60 years on the throne. The only other to celebrate a Diamond Jubilee was Queen Victoria in 1897.
Like blue lobsters, the Hale-Bopp comet or Queen Elizabeth's own Andamooka opal necklace, Diamond Jubilees are rare, so we're paying attention.
In anticipation of the BBC's star-studded Diamond Jubilee concert coming up next week, we're looking for your song dedications to the Queen. Whether you're a hardcore royal watcher with a penchant for Will and Kate, or a member of the commonwealth who couldn't pick Prince Andrew out of a crowd, why not join the fun and send the Queen a message through a song?
We'll start the list of song dedications with Avril Lavigne's "Keep Holding On." (If the Queen holds on for another 10 years, there will be a history-making platinum jubilee.)
Add your song dedication to Queen Elizabeth in the comments below, or tweet it using the hashtag #cbcjubilee.
