I have read several local/national newspaper reviews from all around the UK - all were very good with the only criticisms being minor and usually to do with some of Cliff's dancing moves ( and who could disagree with that!?) - and with the reviewer usually seeming very pleasantly surprised. The Shads in particular were never rated as anything less than great (eg 'dazzling') and often were said to steal the show entirely. 'Cliff's 'In The Pink' show is Solid Gold' was a typical headline.
Sad how the critics have loved to knock Cliff for no reason over the years. But this show should silence them for once and all - and it appears that in the UK it might have already done that.
