Listen to BBC Radio 1 Vintage's The Best of The Official Chart special

Mark Goodier returns for a rundown of this week's Top 40, plus the biggest Number 1 singles ever are celebrated.

BBC Radio 1 turned 50 years old over the weekend, and the station celebrated the very best of The Official Chart from over the last half a decade.

Current host of the Official Chart, Greg James, took us through the biggest Number 1 hits in UK chart history, while past presenters such as Tony Blackburn and Mark Goodier returned to reflect on their time taking the nation through the Official Singles Chart Top 40. Mark, who hosted the show for ten years, even returned to read out this week's Top 40. Amazing.

The one-hour broadcast, originally airing last night (October 1) at 6pm, celebrated the Top 3 longest-reigning Number 1 singles of all-time, Bryan Adams' (Everything I Do) I Do It For You, Drake's One Dance, and Wet Wet Wet's Love Is All Around, the latter famously deleted from sale by the band themselves.

Posthumous Number 1 hits from Buddy Holly, Elvis Presley and John Lennon were celebrated, as was the biggest selling single of all-time, Elton John's Candle in the Wind '97, released in memory of the late Princess Diana.

And it wouldn't be an Official Chart special without some juicy chart battles. Blur vs Oasis, Wham! vs Frankie Goes To Hollywood, and of course, Joe McElderry vs Rage Against The Machine, which was the huge battle for Christmas Number 1 in 2009.

The biggest charity singles are also given spotlight, including Artists for Grenfell's Bridge Over Troubled Water, 1987's Ferry Aid, and Band Aid's four iconic versions of Do They Know It's Christmas?. We're two months early, but why not check the Top 20 biggest selling Christmas hits of all-time?
