Bryn came to London from Lancashire in the late sixties and joined "Les Fleur de Lys" a motown/soul band which became house band for Atlantic Records in England. He left the band in ’69 and travelled to California; from there he toured extensively in the US in various American bands and was a founder member of Wolfgang, a band put together and managed by the legendary Bill Graham, appearing on bills with such artists as Led Zeppelin, Jefferson Airplane and others. 1973 he returned to England and was signed to Island Records where he made his first LP "Let The Days Go By".

He has recorded as a session guitar player with top musicians including Chris de Burgh, Joan Armatrading, Cliff Richard and Gerry Rafferty.
Bryn also writes his own songs, and has had several of his own compositions recorded by other artists including Lulu, Sandy Denny, and Mary Black, and many of his worship songs are sung in christian fellowships across the world.

Bryn is particularly recognised a remarkable exponent of the slide (or bottleneck) guitar, a technique derived from the blues.” Russ Bravo for the Christian Herald writes ”what a delight superbly played blues and slide guitar is; and the delight is multiplied when the music comes from the excellent Bryn Haworth, wrapped in songs of strength and encouragement”.

Bryn recorded a further album for Island, ("Sunny Side Of The Street"), and then continued his career as a solo recording artist with A&M Records where he recorded "Grand Arrival" and "Keep The Ball Rolling". During this period he made numerous radio and TV appearances, including sessions for John Peel and appearances on BBC’s Old Grey Whistle Test, as well as touring extensively in England and Europe supporting such artists as Traffic, Bad Company, Gallagher & Lyle and Fairport Convention.

In 1974 Bryn and his wife Sally became Christians and this powerful experience has brought a strong gospel influence into his music. From ’88-92 Bryn was on staff at the SWLondon Vineyard Church developing worship teams and setting up a prison ministry, and since then Bryn has regularly performed concerts in prisons across the UK and run workshops to help inmates develop their music skills.
Bryn also travels extensively performing concerts and leading worship seminars and guitar clinics throughout the world in a wide variety of venues including concert halls, theatres, pubs, clubs, churches and prisons.

He has recorded 11 further albums, and his latest album, “Keep The Faith”, is released on Bryn’s own label, Bella Music.
