Sunday, Monday, Happy Days,   Tuesday, Wednesday, Happy Days,   Thursday, Friday, Happy Days,   Saturday, what a day,   Groovin' all week with you.      These days are ours   Happy and free. (Oh Happy Days)   These days are ours   Share them with me.(Oh Happy Days)      Goodbye grey sky, hello blue,   'cause nothing can hold me when I hold you.   feels so right it can't be wrong,   rockin' and rollin' all week long.   (Chorus)      These Happy Days are yours and mine (oh Happy Days)   These Happy Days are yours and mine (oh Happy Days)   These Happy Days are yours and mine, Happy Days.
