The Moody Blues are a progressive rock band from Britain who achieved popularity in the late sixties. Their hits include Nights In White Satin, Forever Afternoon (Tuesday Afternoon), Question, and I'm Just A Singer (In A Rock And Roll Band). They were invited to Woodstock, but refused.
They began in the mid sixties upon the rise of the British Invasion, and at the time were similar to other British bands of the time. Eventually, they developed their own style as a symphonic rock band.
