Bob Delyn a'r Ebillion (transl. Every Harp and the Pegs)^[1] are a folk-rock group from Wales, who sing both in Welsh and Breton.^[2]

Fronted by Prifardd (transl. Chief Bard) Twm Morys, Bob Delyn a'r Ebillion are a major figure in the history of Welsh folk revival in the early 1990s.^[2] Their music combines an eclectic array of influences and instruments with more traditional Welsh folk and roots sounds.^[2]

Their debut album was released in 1990, which was according to Blake (2017) a time "when Welsh – in the arts and in daily life – was at a particularly low ebb."^[2] He goes on to state that the band were one of the first to form what was the inception of a new era of Welsh language music, which would lead on to the increased relevance of the language across the country.^[2]

One track written by the band, Cân John Williams, is typical of their identity. It speaks of John Williams, a man residing in a valley in the Black Mountains, who was one of only five Welsh speakers left.^[2]

Another track, Fy Mendith ar y Llwybrau, recalls a trip made by Morus to Canada and his longing for home during the journey.^[2]

The group's use of both Welsh and Breton has been praised, in tracks such as Meur a Wech, for showing "both the similarities and the differences between the two ancient Celtic languages."^[2]

In 2017 they released their first album in thirteen years, entitled Dal i ‘Redig Dipyn Bach.^[3]
