The Waterboys are a Scottish/Irish folk rock band formed in Edinburgh in 1983 by Scottish musician Mike Scott. The band's membership, past and present, has been composed mainly of musicians from Scotland and Ireland with Edinburgh, Dublin, Spiddal, New York and Findhorn, serving as homes for the group. Mike Scott has remained as the only constant member throughout the band's career. They have explored a number of different styles, but their music is mainly a mix of Celtic folk music with rock and roll.

After the release of their debut The Waterboys began touring. Their first show was at the Batschkapp Club in Frankfurt in February 1984. The band then consisted of Mike Scott on vocals and guitar, Anthony Thistlethwaite on saxophone and mandolin, Wallinger on keyboards, Roddy Lorimer on trumpets, Martyn Swain on bass and Kevin Wilkinson on drums. John Caldwell from Another Pretty Face also played guitar, and Scottish singer Eddi Reader sang backing vocals for the band's first two concerts. The band made some new recordings and over-dubbed old material in late 1983 and early 1984 which were released as The Waterboys' second album, A Pagan Place, in June 1984. The "official" Waterboys line-up at this time, according to the sleeve of A Pagan Place, was Scott, Thistlethwaite, Wallinger and Wilkinson, with guest contributions from Reader, Lorimer and many others.  A Pagan Place was preceded by the single The Big Music. "The Big Music", the name of the single's A-side track, was adopted by some commentators as a description of The Waterboys' sound, and is still used to refer to the musical style of their first three albums. The release of the album was followed by further touring including support for The Pretenders and U2 and a show at the Glastonbury Festival.  The band began to record new material in early 1985 for a new album, with Wilkinson leaving the band to join China Crisis. Late in the sessions future Waterboy Steve Wickham added his violin to the track The Pan Within; he had been invited after Scott had heard him on a Sinead O'Connor demo recorded at Karl Wallinger's house.  The Waterboys (officially a trio of Scott, Thistlethwaite and Wallinger with a slew of guests) released their third album, This Is the Sea, in October 1985. It sold better than either of the two earlier albums, and managed to get into the Top Forty. A single from it, "The Whole of the Moon", reached number 26 in the UK. Promotion efforts were hampered by Scott's refusal to perform on Top of the Pops, which insisted that its performers lip sync. (However, in Southeast Asia, particularly in the Philippines, when the New Wave era started around this period, the group's biggest hit single out of this third album was "The Pan Within", aside from "The Whole of the Moon" and "Don't Bang The Drum".) The album release was followed by successful tours of the UK and North America with Wickham becoming a full-time member, Marco Sin replacing Martyn Swain on bass, and Chris Whitten replacing Kevin Wilkinson on drums. Towards the end of the tour Wallinger left to form his own band, World Party, and was replaced by Guy Chambers. At the same time, drummer Dave Ruffy replaced Chris Whitten.
