Here's the part sung by Dido:
My tea's gone cold, I'm wondering why, I got out of bed at all
The morning rain clouds up my window, and I can't see at all
And even if I could it would all be grey,
but your picture on the wall
It reminds me that it's not so bad, it's not so bad
And the bass part played troughout the song:
[--0-----0-8-----8-10-------10-3---2--] repeat all along the song
[E] [-------------------------------------]
