The group was produced by Gerry Granahan. Their debut for Roulette Records was the single "The Crawl", but the group's second single, the Ribbon Records release "You Were Mine", was their biggest hit. It peaked at #21 on the Billboard Hot 100 in 1959. Later singles included "I Can't Say Goodbye", "Marianne", and "My Girl" (all 1960); "I Can't Say Goodbye" was the only charter, peaking at #90 in the U.S.. In 1962 the group reappeared on Taurus Records with "You Were Mine for Awhile" and "Blacksmith Blues" on Hamilton Records; three other singles followed on Taurus, but the group never returned to the charts. The group lasted as long as 1967 before disbanding for good. Adams went on to release some solo singles and had a highly successful songwriting career. Granahan had a solo hit the same year The Fireflies had their only Top 40 hit. The original members involved in the song "You Were Mine" in 1959 were Paul Giacalone, Richie Adams, Lee Reynolds, John Viscelli, Carl Girosli. Background singers also included Jerry Granahan and the Perone Sisters. The songs "You Were Mine" and "I Can't Say Goodbye" were both written by Paul Giacalone. 3) The Fireflies consist of Moreno (Bass), Ben (Guitar), Sander (Vocals) and Brent (Drums). They participated in the Eurosong for kids preselection in Belgium (September 2006), and placed second after 'Thor!', the youngest candidate in the final show, on October 1st. They don't exist anymore. 4) The Fireflies were a major live act in Sault Ste Marie, Ontario throughout the 1960's. They never recorded. Members included Howard Hall and Rick Rogers ((Those) Rogues). 5) An indie folk/pop band that is no longer. The Fireflies is no longer a band because all of those songs were written about the same girl. Songs are no longer written about her. That is why The Fireflies is no longer a band. When new songs are written about new things by the same person (Yuri) you will be alerted. Thanks.
