By 1981 Beaton was a resident singer at the Bob Burns Restaurant in
Woodland Hills, California, performing a variety of music including country, folk, pop, rock, and standards. While at Bob Burns, wealthy real estate broker James Gary, who was of Scottish descent, became a fan of Beaton's and invested in an album of Scottish music; this resulted in the two becoming business partners to form Glenfinnan Records (
Glenfinnan is the place name of where the
Jacobite rising of 1745 began). In 1986 Beaton fully transitioned to performing folk music that was primarily Scottish in origin or subject, although his repertoire included songs in the folk music genre that were not purely Scottish (such as by
Gordon Lightfoot and
Stan Rogers). In 1993 it was reported that Beaton was appearing at several dozen festivals that year. Also in 1993, it was stated that Beaton was "the featured performer at all of the major Scottish festivals, including Maxville and Fergus Highland Games in Canada, North Carolina's Grandfather Mountain, California's Santa Rosa and Cost Mesa, and the Stone Mountain Highland Games in Atlanta, Georgia." In 1994 it was said that he gave about 75 performances a year, mostly at Scottish festivals. In 1996 he started hosting guided tours to Scotland.
The Times Scotland noted Beaton's performance style, stating "mixed in with the tender ballads from his homeland were bawdy family favorites such as "You Cannae Shove yer Granny aff a Bus" and a healthy dose of Glaswegian banter."
The Herald Scotland described him as "a tall, distinctive figure with . . . (an) easy-on-the-ear singing style." The Virginia Gazette said "Beaton's voice and guitar are clear, thoughtful and sensitive. Singing sentimental ballads, his rich (singing voice) evokes a tear; his sly Scot's humor provokes laughter; rousing interpretations of patriotic songs invite enthusiastic cheers." He interspersed narratives of Scottish history and wit amongst songs in his musical sets. Beaton gave what would become his last public performance on the
Isle of Harris on 11 June 2011. He performed
Piper to the End by
Mark Knopfler, which he was planning to include on his next album. ==Guitars==
