If Practice Makes Perfect lyrics

And while you're sleepin'
It must be welded into your mind
And if practice makes perfect
Then I'm leavin' you perfect this time

Over, and over, and over again

I have tried to do right by you
But over and over, the things I do
Just prove to be over and over untrue
[ Lyrics from: http://www.lyricsmode.com/lyrics/j/johnny_rodriguez/if_practice_makes_perfect.html ]
But I'll take the blame, and I'll bear the shame
It's not your fault, no darlin', it's mine
And if practice makes perfect
Then I'm leavin' you perfect this time

So how do I look, leavin'
It must be welded into your mind
And if practice makes perfect
Then I'm leavin' you perfect this time

If practice makes perfect
Then I'm leavin' you perfect this time
