Moody Blues members Justin Hayward, John Lodge and Graeme Edge will be in Nashville to witness a live performance of music from the acoustic album, Moody Bluegrass: A Nashville Tribute to the Moody Blues. The album includes bluegrass versions of "Nights in White Satin," "Your Wildest Dreams" and other Moody Blues hits. The Oct. 23 show at the Ryman Auditorium will feature performances by many of the musicians who performed on the album released earlier this year. Among the participants are John Cowan, Stuart Duncan, Aubrey Haynie, Alison Brown, Jon Randall, Harley Allen and Tim O'Brien. The concert precedes the International Bluegrass Music Association's World of Bluegrass Week taking place Oct. 24-30 at the Nashville Convention Center.
