Footage has emerged of Paul McCartney singing behind the scenes on the set of Pirates Of The Caribbean, while Johnny Depp completely fangirls over him.

The Beatles star made a cameo in Dead Men Tale No Tales, and the clip sees him serenade the crew with Maggie Mae, which features on their 1970 Let It Be album. 

The song is actually a traditional Liverpudlian folk song or sea shanty about a prostitute who robbed a sailor.
