Sam and the Womp have crashed into the number one spot in the charts with their debut single Bom Bom.
Chart-toppers Sam and the Womp
The London-based big band collective's song sold 107,000 copies of the feel-good summer single to make it one of the fastest-selling tracks of the year, according to the Official Charts Company.
The brass-heavy dance-track, which featured in coverage of the Olympic Games pushed Rita Ora's How We Do (Party) off the top spot.
Frontman and trumpeter Sam Ritchie gave "massive womps" to everyone who bought the song.
"We really didn't expect this at all for Bom Bom to go all the way to the top when we were writing it in a muddy field a couple of years ago, with Mr Aaron Audio falling off his chair," he said.
The band join the likes of DJ Fresh, Ora, rapper Wiley, Florence and the Machine and Cheryl Cole in the league of artists who have had a single that managed to break 100,000 sales in its first week of release this year.
Two other new entries broke the top 10, Taylor Swift's We Are Never Ever Getting Back Together and Devlin featuring Ed Sheeran with (All Along The) Watchtower, their cover of the Bob Dylan and Jimi Hendrix classic.
Harder Than You Think, by legendary rap group Public Enemy, surged back into the top 40, jumping from 56 to 11 after first entering the chart at the start of August.
In the Official Album Chart, Emeli Sande continues to ride a post-Olympics wave, with Our Version Of Events topping the chart for the fifth week in a row.
Indie band Bloc Party were the highest new entry in the album chart with Four, their first new release in three years, which charted at number three.
