Sixty, Off-Key [Verse 1] The windows down, the radio high, you find a tune and let it fly. The notes take turns we never planned, and we're your very biggest fans. [Chorus] Sixty, still singing off-key in the car — happy birthday, Mum, our favourite star! Tomatoes piled high in that old summer van, so sing it off-key, as loud as you can! [Verse 2] You plant a few, a few grow more, red little suns beside the door. We pack the van for summer days, your song goes with us all the way. [Chorus] Sixty, still singing off-key in the car — happy birthday, Mum, our favourite star! Tomatoes piled high in that old summer van, so sing it off-key, as loud as you can! [Bridge] It's in the ordinary things, the joy a journey with you brings. No perfect note could say it true: the best part, Mum, is being with you. [Chorus] Sixty, still singing off-key in the car — happy birthday, Mum, our favourite star! Tomatoes piled high in that old summer van, so sing it off-key, as loud as you can! [Outro] Happy birthday, Mum — here's our song for you. Turn it up; we'll sing it with you too.
