A series of outside broadcasts from this year's Service Spectaculars
Barri Haynes introduces highlights from the 1973 show which features:
The Royal Artillery Motorcycle Display Team, The Musical Ride of the Household Cavalry and the Finale in which the Massed Bands and Corps of Drums parade as a grand finale to the Tattoo from Cardiff Castle, a delightful setting for this traditional spectacle - an entertainment which is uniquely British.
