Way back in the 1960's (or was it the 70's.......? it's all a bit of a blur these days) I used to have an album (vinyl, of course) that contained a long instrumental piece that finished with some thoughtful lyrics. The final couple of lines were "Riders together on this starship of stone, Living together, trying together, dying alone". I have been focusing my fast dissappearing brain cells (I am bravely using the plural there....) for some time without any success. Can anyone help me with identifying the band/album/song please?
