dunno about the start I think it's Cmaj E G but when she starts singing it goes

Cmaj E G /A G A G A\G F E F G

My friends Tigger and Poo, we're always there for each other

Cmaj E G G A G F G A G F E/F/G
You'll see just how fun it can be, there's so much there to discover

A Dmaj A Dmaj

And if I need I'll call away(??) Buster might save the day or Piglet Muffy or Roo

A Dmaj

Eeyore has a part to lend Rabbit has an ear to bend

A B C D E F G/A
And all we're missing is you

Last bit is as the first two verses but up a key to Dmaj

hope it works
