Bartholomew's work as a busy session vocalist and instrumentalist in Hollywood drew the attention of Takoma Records Denny Bruce in 1981 and Bart wrote produced and performed the Takoma records release "The Roulettes", a pop rock project of his own. In recent years Bart had gone back to using his original stage name of "Bartholomew" and was in production of a new album that focused on his folk-classical musical roots. The new project, tentatively titled "Three Cornered Hat", was produced by brother Theo Bishop at Native Language Studios in the Los Angeles area, with a tentative release in 2008. It was to feature the string arrangements and performances of another brother, Jayson Bishop, on cello and string bass, as well as Theo's keyboard work. The brothers entertained distribution opportunities around the world, particularly to accommodate a European tour scheduled for summer 2009, along with Bart's son Graham's act, "Senors of Marseille".
