Stricken with polio at the age of nine, doctors said that Joni Mitchell would never walk again. But in the hospital’s children’s ward she spent all her time singing at the top of her lungs and believing she would walk again. And she did. Her album, “Blue,” released on Reprise Records in 1971 is # 30 on Rolling Stone’s 500 Greatest Albums of All Time. An original copy is worth up to $150.00 today. Her first album for Reprise from 1968 simply called “Joni Mitchell” can now sell for up to $200.00.
