Abraham, Martin & John lyrics

Has anybody here seen my old friend Abraham? Can you tell me where he's gone? He freed a lot of people But it seems the good they die young You know, I just looked around and he's gone Anybody here seen my old friend John? Can you tell me where he's gone? He freed a lot of people But it seems the good they die young I just looked around and he's gone Anybody here seen my old friend Martin? Can you tell me where he's gone? He freed a lot of people But it seems the good they die young I just looked 'round and he's gone Didn't you love the things that they stood for? Didn't they try to find some good for you and me? And we'll be free Some day soon, and it's a-gonna be one day Anybody here seen my old friend Bobby? Can you tell me where he's gone? I thought I saw him walkin' up over the hill With Abraham, Martin and John
