You're My Number One

 is the last song of Series 3 in 2001.

Lyrics
You're my favourite person You're my number one You're my number one (Oooh!) Whenever we're together We're having fun We're always having fun (Oooh!) 'Cause you're my number one You're my number one

Wherever we go We're always together Everywhere we go We're never far apart Wherever I go I take you with me Everywhere I go I take you in my heart 'Cause you're my number one

You're my favourite person You're my number one You're my number one (Oooh!) Whenever we're together We're having fun We're always having fun (Oooh!) 'Cause you're my number one You're my number one

Everything we do It's always exciting It's more fun with two We'll never be apart Whatever we do There'll always be music It's just me and you I'm always in your heart

Let's go on an adventure Let's go outside and play Doesn't matter if it's hot or cold Or raining today 'Cause you're my number one You're my number

You're my favourite person You're my number one You're my number one (Oooh!) Whenever we're together We're having fun We're always having fun (Oooh!) 'Cause you're my number one Still my number You're my number one You're my number one!
