Teeth 'n' smiles

June 9th 1969. A warm night in Cambridge. A rock band plays the May Ball gig for 120 pounds. A great deal of champagne, a good deal of hashish, some acid and a very little preludin'. And the band still have three sets to play. 'Teeth 'n' Smiles' was first performed at the Royal Court Theatre, London, in September 1975.
