The first reference we can find to Bagatelle is an advert in October 1978 for "Bagatelle - ex-Boulder Band." This caused us to look further back as the Boulder Band were popular in Dublin night spots.

The Boulder Band first got mentioned in the papers a year earlier in July, 1977 as they were about to appear in RTE's summer show, "Hello Summer." The show would end up being panned by critics, but the band were given a favourable review. The line-up at the time included ex-members of the Elastic Band, John O'Brien (guitar), Paul Fairclough (drums), Ken Doyle (bass), and Marion Byrne (vocals and sister of folk singer Anne Byrne); and with them was Breda Maher (wife of songwriter Mick Maher).
