Bob Wingrove notes "Caretaker D R Griffiths was a caretaker and a respected Welsh poet under the Bardic name of Amanway,
and brother to former South Wales Miners' Federation President Jim Griffiths, (MP for Llanelli 1936-70) and this film reflects much of his story.
In the distance you can see what I think is possibly a municipal bus at what must have been the 1950 Eistedfford (that year it was held in Caerphilly), then there is what I think is a Rees and Williams 'decker (didn't they always have Guy Arabs after the war?) and a James of Ammanford Leyland Titan PD, fleet number 207 ." 207 (FTH681) was an all-Leyland Titan PD2/3.
