Taped at Nashville's WSM radio in 1951, these early-morning broadcasts (each 15 minutes long) reveal a wonderfully relaxed Hank Williams: He jokes around, promotes Mother's Best Flour and delivers spine-tingling performances of both old hymns and classic originals like "Hey, Good Lookin' " and "California Zephyr." In all, 72 radio shows never before released in their entirety, adding up to 18 hours of down-home entertainment. A feast.

“Help Me”

Joni Mitchell wrote and recorded this song for her album Court and Spark, but she had to switch from her regular band to make the song sound exactly the way she wanted. "I had attempted to play my music with rock & roll players," she told Rolling Stone. "They’d laugh, 'Awww, isn't that cute? She's trying to teach us how to play.'" Mitchell switched to a jazz band, Tom Scott’s L.A. Express, and scored the biggest hit of her career in the process.
