get it while you can

you've got to get it while you can, time and time we've gone no man, tomorrow will become today, it's there to take it if you try, everybody's having fun, so why be the one, who's out in the cold, don't let the future pass you by, go ahead and give it a try, you've got to fight for number one, you see the story's just begun, everybody's having fun, so why be the one, who's got to be told, by the time you get to something, you'll see the writing on the wall, you're living in the land of maybe, tomorrow never comes at all, from times remembered and the times in between, you'll find you're living your life in a dream
