Composed by Dion DiMucci and Ernie Maresca. The lyrics are sung from the point of view of a man whose former girlfriend, Sue, was unfaithful. He warns all potential lovers to avoid her at all costs, as Sue “runs around” with every guy she meets and never settles down with any man in particular. He advises; “now people let me put you wise, Sue goes out with other guys” and suggests that potential suitors should “keep away from Runaround Sue”. Dion stated in his autobiography The Wanderer that, although his wife’s name was Susan, Runaround Sue had nothing to do with her. However, when Dion and his wife were interviewed on The Oprah Winfrey Show in 1990, they said the song was about her, Sue. The song reached No.1 in Canada, New Zealand, USA. It peaked at No.2 in Australia and No.11 in the UK.
