charlie bowman recorded "Nine Pound Hammer" and also wrote "Roll On Buddy". it goes ....roll on buddy roll on...you wouldnt move so slow if you knew what i know, roll on buddy roll on...havent been able to find roll on buddy lyrics and chords on the net. But i have a vinyl copy of the song "Roll On Buddy' that my grandfather gave me. Charlie Bowman was my grandfathers dad. He was my great grandfather although i never met him...he died in 1962
