Selfish Gene

I know I should stay, but my blood is too weak
 I've got a wandering soul, that's gotta roam
 I do love you baby, but you must let me go
 'Cause my selfish gene must go on
 I never got you no flowers, I never got you shampagne
 So why expect me to change my ways?
 ...now
 I'm the king of the losers, that's all I have in my name
 But the selfish gene must go on
 Yeah, the selfish gene must go on
 The selfish gene must go on
 I'll be back to you baby, and it's gonna get worse
 To hang out with me is some kind of curse
 You know that I love you, but I must be on my way
 'Cause my selfish gene must on
 'Cause my selfish gene must go on
 'Cause my selfish gene must go on
 'Cause my selfish gene must go on
