All the fools who await your return May we tell them the truth There's no way you can turn back the clock Never cling to your youth How unfortunate it must have been Life is only a race You're so old that it might take a crane Just to lift back your face Scientific so scientific Scientific so scientific But you were walking on gla** How unstable we bolt with the horse Setting music to muscle All the fallers who litter the course As we run to the castle Scientific so scientific Scientific so scientific But you were walking on gla** Careful - you're walking on gla** You're walking on gla** When you say that the sun does not move Did it show you the answer When the ships do not fall off the world Does it mean there's a wall there You say the sun does not move Careful - you could be walking on gla** He could see that the earth was a mover And the sun was a mother But he was walking on gla**
