On Tuesday, it'll be 1981
On Tuesday, 5 live will be going back in time. To 1981.
So as we build up to Friday's celebrations - 5 live will take a look back three decades at what was going on the last time the country had a big Royal Wedding to look forward to.
Gabby adds a sporting flavour with Steve Perryman from Tottenham Hotspur's FA Cup winning team, Scottish footballer John Wark who won the UEFA Cup with Ipswich Town and was player of the season in 1981, and Steve Davis who three decades ago won his first snooker Masters title.
Later in the day, Richard Bacon will chat with musician and cartoonist Rolf Harris, who was part of the official wedding commentary team in 1981. He'll be joined by magician Paul Daniels, whose Saturday night magic show was attracting huge ratings in the 1980s.
So that's just a bit of what we are doing on Tuesday.
But what were you doing in 1981? Tell us about the fashion you were wearing, the music you were listening to, TV you loved and the cubes you were solving in the comments below.
