Willie Nelson is on a roll! Nelson's next album, "Band of Brothers," hits stores Tuesday the 17th, but Willie says he had so many songs that he ended up recording two albums rather than just one. The country legend tells Billboard.com he'll follow next week's release with "December Day" sometime this fall. Nelson says for "Band of Brothers," he'd record "an idea" and send it to producer Buddy Cannon, who would "hire musicians and cut the whole track from that," then he'd add vocals to finish the song. For "December Day," Willie says he'd "been waiting" a long time to make a record with his own group and so followed a different formula to make the second album come to life. Willie Nelson may be 81 years old, but it doesn't sound like he's planning on slowing down anytime soon.
