Originally from Londonderry, Feargal Sharkey joined the Undertones shortly after their formation in 1975
The punk band had several UK hits, with songs such as "Teenage Kicks", "Here Comes The Summer", "My Perfect Cousin", "Wednesday Week" and "It's Going to Happen!".
But, according to Wukipedia, the band split in 1983 citing musical differences, with Sharkey pursuing a solo career and other members of the band forming That Petrol Emotion the following year
