Caroline Wolters Mastenbroek has 51 Cliff Richard concerts.

Sir Cliff Richard (born Harry Rodger Webb, 1940-10-14, in Lucknow, India) moved as an 8-year-old to the UK, where it would be 10 more years before he and his group The Drifters emerged in the UK charts for the first time with 'Move It'. Cliff was heavily influenced by Elvis, imitating him shamelessly during the first couple of years of his career. Something which he openly admits, and fully acknowledges that without Elvis, he and many others would never have happened.
