Hustle

From the album ONE ON ONE (1977)

Pull the stops out, watch my hustle
Would you believe I was once a. . .[?]
Would you believe I was even as shy as a child
It's so hard for the mind to fathom, so don't try

I feel like tripping the light fantastic. I've never been more enthusiastic
My mind. . . [?]
I'm a stone gladiator on a mood elevator. In the thick of the fight, I just smile
Pull the stops out, watch my hustle
(repeat)
