NME reveals the extent of Cliff's throat problems:

CLIFF RICHARD had to miss his guest spot in ATV's "Jack Jackson Show" on Wednesday because of throat trouble, and there is a big doubt whether he will be fit enough for "Oh Boy!" tomorrow (Saturday). He also had to cancel his appearances at the Lyceum Ballroom, London, where he had been at the centre of sensational scenes on Monday.
Rioting among the dancers broke out as he made his entrance for the first of the week's cabaret spots in this major London dance hall.

Rock 'n' roller Vince Taylor, who was in the audience, said: "They even threw people at Cliff! I don't think they liked his pink jacket."

On Tuesday it was announced that Cliff would be unable to fulfil his engagement as he was suffering from laryngitis. The extent of his illness was more serious than was originally thought.

Young singer Terry Wayne ably stood in at short notice. Billy Fury deputised in the Jack Jackson Show on Wednesday.

Due to his condition, there is grave doubt whether Cliff will be appearing on "Oh Boy!" on Saturday night. Jack Good expressed concern as Cliff was due to sing five solo numbers and three duets on the show.

Next week Cliff is due at EMI recording studios to record his new LP. There will be an audience of boys and girls from different countries.
