Television personality Piers Morgan, a former editor of the Daily Mirror and of The Sun's Bizarre pop column, has said that during the late 1980s, at Kelvin MacKenzie's behest, he was ordered to speculate on the sexuality of male pop stars for a feature headlined "The Poofs of Pop". He also recalls MacKenzie headlining a January 1989 story about the first same-sex kiss on the BBC television soap opera EastEnders "EastBenders", describing the kiss between Colin Russell and Guido Smith as "a homosexual love scene between yuppie poofs ... when millions of children were watching".

Answer this question, if possible (if impossible, reply "unanswerable"): Which BBC show's homosexual kiss did The Sun report on?
EastEnders
