What happens when Paul McCartney asks, “What are you doing for the next few years?” For Lawrence Juber, you think about it for a nano second, before saying “I guess I am playing with you.”  The session guitarist, musicologist, former Wings guitarist and Grammy-award winning composer with 25 albums to his name describes rehearsing with Paul and Linda before their next tour. McCartney wanted to record some tracks, but his favorite studio, Abbey Road, was unavailable -- so he built an exact reproduction of Abbey Road inside his own studio. He explains how composers and performers get paid a meager amount from music streaming, and why the real money is in television and movie soundtracks. The music business model has changed from record sales to live performances and merchandise sales.
