Amazing pre-war vintage London bus drive-past - London Bus Cavalcade - 1

Watch the oldest Leyland bus in the world, a First World War London General 'B-type' bus, a K-type, S-type, NS-type, with two STL-class AEC Regents and up to a little Country Area Leyland Cub, newly-restored GreenLine AEC Regal coach and pre-war RT pass by the camera, taking part in the once-in-a-lifetime London Bus Cavalcade on 22 June 2014.
Most of these buses are very rarely ever seen in public, usually static in museum galleries, so this is a truly special sight.
With thanks to my friend Steven Quy for managing my camera for me whilst I took necessary stills.
