By early 1976, the strain of success (and the discomfort of being a man in his late 20s in a teen band) had taken its toll on bassist Alan Longmuir, who decided to leave the group. He was replaced for seven months by 17-year-old Ian Mitchell from Northern Ireland; he was the first band member born outside Edinburgh, Scotland. With Mitchell, the group released an album titled "Dedication" (1976), and hit the charts with a cover version of the Dusty Springfield song, "I Only Want to Be with You. " The song reached US No. 12, as well as "Yesterday's Hero" (featuring live material from a 1976 personal appearance in Toronto's Nathan Phillips Square), and "Dedication".
