Happy, happy, oh my friend Blow out candles once again Leave the presents all inside Take my hand And let's take a ride Backwards down the number line You were eight and I was nine Do you know what happened then? Do you know why we're still friends? Laughing all these many years We've pushed through hardships, tasted tears Made a promise one to keep I can still recite it in my sleep Every time a birthday comes Call your friend and sing a song Or whisper it in to his ears Or write it down, just don't miss a year You decide what it contains How long it goes but this remains The only rule is it begins Happy, happy, oh my friend You decide what it contains How long it goes but this remains The only rule is it begins Happy, happy, oh my friend You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) Happy, happy, oh my friend (Going backwards down the number line) You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) And when I see you coming down the line with eyes wide open Somewhere in between the passing future where you drift in time And you can see a different point of view You decide what it contains How long it goes but this remains The only rule is it begins Happy, happy, oh my friend You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) Happy, happy, oh my friend (Going backwards down the number line) You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) Happy, happy, oh my friend (Going backwards down the number line) You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) Happy, happy, oh my friend (Going backwards down the number line) You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends) Happy, happy, oh my friend (Going backwards down the number line) You decide what it contains (All my friends) How long it goes but this remains (Going backwards down the number line) The only rule is it begins (All my friends)
