Sixties British rock star Cliff Richard, once called the "bad boy of pop" and "too sexy for television," became a devout believer and disciple of Jesus. Back in the '70s, he visited missionary outposts in the Sudan and refugee camps in Bangladesh as part of a mission trip for Tear Fund. In his book about his conversion to Christianity called Which One's Cliff?, he tells how "the first morning, I must have washed my hands a dozen times. Whenever we stopped, I made a beeline for the communal tap or the well; I didn't want to touch anything, least of all the people. Everyone in those camps, even the babies, was covered in sores and scabs.

"I was bending down to one little mite, mainly for the photographer's benefit, and trying hard not to have too close a contact, when someone accidentally stood on the child's fingers. He screamed out, and as a reflex, I grabbed hold of him, forgetting all about his dirt and his sores. I remember now that warm little body clinging to me, and the crying instantly stopped. In that moment, I knew I had an enormous amount to learn about practical Christian loving, but at least I'd started."
