In 1984 the band issued the single "Runner", a cover of the song by Ian Thomas, which had been written in response to cancer sufferer Terry Fox and his run across Canada for cancer awareness. Fox had succumbed to the cancer before finishing. The Manfred Mann version featured Chris Thompson on lead vocals and Mick Rogers on backing vocals. The song was a non-LP single in the UK but was included on the US release of "Somewhere in Afrika". It was a top 40 hit in both Canada and the US and was used during ABC's broadcasting of the 1984 Summer Olympics and in the film "The Philadelphia Experiment". At 22 on the Hot 100 it was their biggest hit since "Blinded by the Light" and was the band's second highest-charting song, as well as their final US/UK chart single.
