If you've seen the film 'Step Brothers', you'll be aware that one of the best moments of Adam McKay's 2008 comedy is one particular song.

'Boats N' Hoes' is first heard when Brennan (Will Ferrell) and Dale (John C. Reilly) interrupt a birthday party to show people their music video - a pitch for their entertainment company - which was filmed on Brennan's dad's boat.

'Boats N' Hoes' has followed both actors around for the last 15 years and on Saturday night in Los Angeles, both Ferrell and Reilly performed the track live on stage with Snoop Dogg at the Greek Theatre.

The gig was the second of Ferrell's 'Best Night of Your Life' concerts, which he staged with multiple guests to raise money for the charity Cancer for College.

Snoop Dogg, of course, co-starred with Ferrell in both 'Starsky & Hutch' and 'Old School'.

They also performed the rapper's song 'Gin & Juice'.
