A Flock of Seagulls was started by Mike Score and his brother Ali in 1979 in Liverpool. Mike, who was previously a hairdresser, played keyboards, guitar, and Vocals, Ali played drums and their friend Frank Maudsley played bass. The band took their name from a line in the song "Toiler on the Sea" by The Stranglers, which appears on their album Black and White. The band added guitarist Willie Woo and Mark Edmondson joined briefly when Ali and Mike had a fall out with Ali re joining when Mark took ill. They then began writing songs. Soon later Willie left allowing Paul Reynolds to join. They then started playing clubs, and soon enough, they got a contract. The choice of their name was between "The Flock of Seagulls" and what it is today. A friend chose "A Flock of Seagulls" because it was a shorter name to write on first time gig
