Here is a real rarity: an excerpt, including the opening credits, from the first episode of the series Bracken, with Gabriel Byrne in the role of Pat Barry.
Many thanks to @g12_el on Twitter for making this available and to Linda for her video wizardry!
Bracken, a rural television drama series, created by Wesley Burrowes, was first broadcast in January 1980. The cast included Gabriel Byrne, who had played Pat Barry in The Riordans, and Dana Wynter. Bracken in turn led to Glenroe which inherited the characters of Dinny and Miley Byrne and ran for 18 years on RTE.
