Livin' On A Prayer [Bon Jovi Cover] - Lothian & Borders Police Choir. Edinburgh Airport -16/12/12 

On 16/12/12, en route to Madrid and whilst sat supping on my Salted Caramel Latte in the Costa Coffee shop in Edinburgh Airport, these guys up and started an impromptu warm-up before scurrying off to sing carols for passengers arriving at the gates.
They are The Lothian & Borders Police Choir and there are much better videos on their own channel: / andrewrusselmusic
