If in Pink Floyd

If I were a swan, I'd be gone
If I were a train, I'd be late
And if I were a good man,
I'd talk with you more often than I do
If I were to sleep, I could dream
If I were afraid, I could hide
If I go insane, please don't put
Your wires in my brain
If I were the moon, I'd be cool
If I were a rule, I would bend
If I were a good man, I'd understand
The spaces between friends
If I were alone, I would cry
And if I were with you, I'd be home and dry
And if I go insane,
Will you still let me join in the game?
If I were a swan, I'd be gone
If I were a train, I'd be late again
If I were a good man,
I'd talk with you more often than I do
