From the YouTube site: "An unprecedented union of the two greatest living jazz singers, ‘Love Is Here To Stay’ celebrates Gershwin’s 120th anniversary with a new recording of timeless American popular standards and jazz repertoire."
Willie Nelson wrote "Crazy" back in 1961, and Country music legend Patsy Cline made it a hit the following year. When Patsy Cline sang country, she could make it sound like a standard right out of the Great American Songbook. Here, putting a smooth jazz spin on the song are Diana Krall, Willie Nelson and Elvis Costello. They performed the number at Willie Nelson's 70th birthday celebration in 2003.
