She's my best friend

What would you think if I sang out of tune,
Would you stand up and walk out on me.
Lend me your ears and I'll sing you a song,
And I'll try not to sing out of key.
Oh, I get by with a little help from my friends.

What do I do when my love is away?
(Does it worry you to be alone?)
How do I feel by the end of the day
(Are you sad because you're on your own?)
No, I get by with a little help from my friends.
