Harry Styles samples The Brothers Johnson's Ain't We Funkin' Now on Harry's House song Daydreaming

As if the '70s influence of Harry Styles' upcoming album Harry's House wasn't evident enough, with its artwork's archetypal geometric décor and Harry's rather fancy flares, it's now been revealed one track incorporates a funky sample from The Brothers Johnson's back catalogue.

With the record's credits now released via streaming services - boasting names including Harry's long-time collaborators Kid Harpoon, Sammy Witte and Tyler Johnson  - eagle-eyed fans spotted a familiar acknowledgement on the song Daydreaming.

Louis Johnson and Quincy Jones, who form funk group The Brothers Johnson, are credited on the track; with Daydreaming sampling their 1978 single Ain't We Funkin' Now.
