That’ll be the day - when you say goodbye
that’ll be the day - when you make me cry
you say you’re gonna leave - you know it’s a lie cause
that’ll be the day when I die

Well, you give me all your loving and your turtle-dovin’
all your hugs and kisses and your money too, we-hella
you know you love me baby - until you tell me maybe
that someday well, I’ll be through

When Cupid shot his dart - he shot it at your heart
so if we ever part and I leave you
you sit and hold me and you tell me boldly
that someday well, I’ll be blue

That’ll be the day - woo hoo
that’ll be the day - woo hoo
that’ll be the day - woo hoo
that’ll be the day
