313. Manfred Mann
For argument’s sake we are going to combine the collective works of Manfred Mann’s various bands and include the Earth Band as one progressive link. Chances are; it is only going to be him who would get inducted anyway. If they did, they would be inducting an artist who transcended infectious British Invasion Pop to the fringes of Progressive Rock. He may have never dominated the charts, but the length of his career was impressive and he would not be out of place in the Hall.
