Hoo-ray, it's Saturday, school's out so watch out.
Look out, find out, come along with me to 73.

Overseas, fly-by-air, just as long as you get there.
Move your feet, down the street, come inside and see a-73.

This was quickly replaced by the FOLLOWING tune:

THEME LYRICS (series 2-6)

Hey you, get ready get on your feet.  Get into gear and hit this street
Hey you, get moving, it's not too far.  You're looking good so come as you are.
Hey you, you never know what you'll see.  When it's through that door with the 73.

Never seen nothing, no, not like this place
Never been no, no way not ever known
Never seen no place nowhere similar.  Not like 73

Hey you, get ready get on your feet  Get into gear and hit this street.
It's you that we wanna see.  So get down to 73.

Get down to 73.  Hey you, get down to 73.

Series 7 and 8 of No. 73 had a remix of the familiar theme (by Ray Shulman). As well as adding handclapping and 'n-n-n-n-nineteen' touches, he also removed the "never seen nothing..." middle-eight.

The Sandwich Quiz (series 2-6)

It's the daring, dazzling, death-defyingly dull, *
devastatingly dangerous, delectable, delicatessenable,
divinely decadent - Sandwich Quiz.

* In the first few series, Ethel sometimes inserted "desperately decimalized" here.

Buchanan's 'Chip Butty Quiz' The song, first heard on the 4th April 1985 edition, went like this:

Salt and vinegar, green mushy peas
Scallops and chips all covered in grease
A big fat sausage, the curry's the biz
Frying tonight, the Chip Butty Quiz

Cleaning the House Song

Purgative, ablutionary,
Clean-up revolutionary,
Dawn + Kim + Neil + Harry,
Manifestly sanitary,
Grab your squeegee, grab your mop,
Shake your tail and shimmy to...
the Duster Muster
Duster Muster, Duster Muster . . .
