Who sings the Martha speaks song?

(Sung)

Martha was an average dog. She went -

(Bark). And- (Woof). And- (Grrrrrr).

(Sung)

But when she ate some alphabet soup, then what happened was bizarre.

(spoken)On the way to Martha's stomach, the letters lost their way. They travelled to her brain and now-

(Sung)

She's got a lot to say. Now she speaks.

(Spoken)

How now brown cow?

(Sung)

Martha Speaks. Yeah, she speaks and speaks and speaks and speaks and speaks...

(Spoken)

What's a caboose? When are we eating again?

(Sung)

Martha speaks...

(spoken) Hey Joe, what d'ya know!

(spoken) My name's not Joe.

(Sung)

She's not always right but still that Martha speaks.

(spoken) Hi there!

(Sung mildly fast)

She's got a voice; she's ready to shout. Martha will tell you what it's all about. Sometimes wrong, but seldom in doubt. Martha will tell you what it's all about. That dog's unique...

(spoken) Testing, one, two!

(Sung)

Hear her speak! Martha Speaks and speaks and speaks and speaks and...

(spoken) Communicates, enumerates, elucidates, exaggerates, indicates, and explicates, bloviates, and overstates and (pant, pant, pant) hyperventilates!

Martha...to reiterate,

(spoken in joyful sing-song voice)

Martha speaks!
