Problem: Background: Bradley Joseph (born 1965) is an American composer, arranger, and producer of contemporary instrumental music. His compositions include works for orchestra, quartet, and solo piano, while his musical style ranges from "quietly pensive mood music to a rich orchestration of classical depth and breadth". Active since 1983, Joseph has performed in front of millions of people around the world. He played various instruments in rock bands throughout the Midwest until 1989 when Greek composer Yanni hired him for his core band after hearing a tape of his original compositions.
Context: Joseph also performed with Sheena Easton for four years as her co-musical director and lead keyboardist. He went from Yanni to Easton and back to Yanni in a few years. "It was a great transition from Yanni because it made me musically aware again", he said in reference to Easton's R&B style. "I went back to where I started but it felt like a new invention."  Wheeler questioned how he got hooked up with Easton; Joseph answered that he was recommended by a former road manager. He was included in a try-out with four others, rehearsed with the band, they then cut it down to two, and rehearsed with Sheena for the final cut. Joseph anticipated they would ask him to do a solo on at least one of the songs he was asked to play during the audition, so he wrote a solo for all three songs, which was ultimately the reason he was hired for the job.  In a 1995 interview, he said that after five years of touring with Yanni and working on his own debut album, he needed a break. Yanni was still building his career and maintained a hectic concert schedule. Working with Easton, on the other hand, was "the best of both worlds". "She just adopted a baby and is pretty settled in", said Joseph. Tour venues with her included Japan, Indonesia, Puerto Rico, and the United States, as well as routine appearances in Las Vegas and Atlantic City. In March 1995, he appeared with her on The Tonight Show with Jay Leno when she performed her new single at the time, "My Cherie".

Background: Robert Wilson "Robb" Royer (born December 6, 1942 in Los Angeles, California) is an American musician and songwriter, best known as a founding member of Bread from 1968 to 1971. While he was with the band, they had a #5 UK/#1 US hit single with "Make It With You". He was replaced by Larry Knechtel in 1971.
Context: In 1982 Royer wrote the song "Quittin' Time" (co-written with Roger Linn) which eight years later was recorded by Mary Chapin Carpenter and won an ASCAP Airplay award. Royer traveled to Nashville to receive the award and stayed with Griffin, who had previously relocated from L.A. to Nashville. Larry Knechtel had also been living and working as a session musician in Nashville. Royer relocated to Nashville in 1994.  Todd Cerney was already a grammy-nominated songwriter when Royer met him in 1994 at Jim Della Croce's house. Cerney had written two top-forty songs (Loverboy's "Notorious" and Restless Heart's "I'll Still Be Loving You," which reached number one on the Country charts). Cerney had established a private recording studio in his home where he engineered a number of other singer-songwriters' albums.  Griffin, Royer and Cerney first collaborated by co-writing the song "Kyrie" in 1994. Knechtel later joined the trio and together they performed and co-wrote songs (including the 1995 song "Slow Train") under the band name "Toast". Toast performed at various Nashville venues including the Bluebird, Third and Lindsley, and 12th & Porter. They wrote and performed their own songs including such titles as "Road Kill," "Knechtelodeon," "No More Smokin'," "Grenadine," "Magdelena," and "Radio Dixie." The group used session drummers for their recordings and performances. The group would later be known as Radio Dixie in 1998. The name change was intended to help with promotion of the group, but the group disbanded by the end of 1998. Royer and Cerney continued to write together, generating additional titles including "Hurtin' Cowboy," "New Orleans Prayer," "I Believe I Kissed an Angel," and "Beside Myself."
