Mary-Lou Helperman: Mrs. Manly Manning
Mrs. Mary-Lou Manly Manning
Mrs. Mary-Lou Moira Angela Darling Helperman Manly Manning!
Scott "Manly Manning": (Spoken) I'm sorry I have to interrupt this musical moment, Mary-Lou, I guess I'll never see you again.
It's time for me to go
Mary-Lou: Oh me, oh my, oh no
Leonard Helperman: I've never been so low.
Dr. Ivan Krank: Oh, where did my dog-man-
Scott and Dr. Krank: Go!?
Scott: I gotta go
I don't know where, I only know
My former friend is now my foe
He couldn't stand the status quo,
I said I'd stay but he said no,
And now - doggone! This dog is gone
I'm moving on
I gotta go!
Mary-Lou: Like a dream, he was here, and now he's gone
He drank my coffee, ate my candy
Dreaming I could stand
By my Manly Manning man,
I thought everything was fine and dandy
Why did he go?
Scott: I'm gone
Mary-Lou: Don't go
Leonard: Oh, no, what have I done?
Mary-Lou: Oh no
Leonard: I kicked him out
He took the keys to freedom
Leonard and Mary-Lou: Now he's going, now he's going, now he's gone
Dr. Krank: My lovely dog-man
Oh, precious, pretty dog-man
Dear, itty-bitty dog I made a man
Mary-Lou: Where have you gone?
Leonard: He took the keys
Dr. Krank: You have the key to my success.
Scott: I'm no one's pawn!
Leonard: He's gone
Mary-Lou: Was I a yawn?
Scott: I'm moving on!
Dr. Krank: (Spoken) Find him!
Dennis and Adele: Where did you go, dog-man?
Pretty Boy and Mr. Jolly: We gotta go where you have gone, Spot
Dennis and Adele: We gotta know, dog-man
Leonard and Mary-Lou: We wanna know where have you gone, Scott
Dennis and Adele: We gotta go there, too
Scott: I'm gone
Mary-Lou: He's gone (Chorus: He's always going, always going)
Scott: I'm moving on (Dennis: Come on, let's run)
Mary-Lou: He's moving on (Pretty Boy: You weigh a ton!)
Scott: And, pardon the pun,
but I am going (Mary-Lou and Chorus: Going, going, going)
without knowing (Mary-Lou and Chorus: Without knowing)
There's a place where I belong. (Leonard and Chorus: Where he's gone)
I'm moving on! (drawn out)
Chorus: Where did you go, dog-man? (x3)
(Leonard and Mr Jolly: Scott! Spot! Scott! Spot! Scott!)
(Mary-Lou: He's gone (drawn out))
All except Scott and Mary-Lou: He's gone
