To the tune of Waltzing Matilda (sung forward, not backward)
{the bit in the {} is the bit which gets replaced in the chorus,
but I guess you knew that already   -   τΏτ }Ahem...

Once a jolly wizzard by the name of Rincewind
Showed me around Ankh Morpork city
{And he shivered as he hid and waited 'til the fights had stopped}
Come and join Rincewind the wizzard and me.
<chorus>
Rincewind the wizzard
Rincewind the wizzard
Come and join Rincewind the wizzard and me
{And he shivered as he hid and waited 'til the fights had stopped}
Come and join Rincewind the wizzard and me.

He took me to the Shades, the palace and the UU tower
The pages of a book and the library
{And he ran from the Luggage, the demons and dragon hordes}
Come and join Rincewind the wizzard and me.

<chorus>

Touring on alone I happened on the city watch
Holding up the law for the people to see
{Carrot's got a way and Vimes is proud (but Nobby's not)} 
Come and join Rincewind the wizzard and me.

<chorus>

I also met the witches, Nanny Ogg and Agnes Nitt
Granny Weatherwax used headology
{But no harm comes to those who respect her and her place inthings}
Come and join Rincewind the wizzard and me.

<chorus>

Before I end this song I must mention one or two more names
Dibbler, Detritus and Vetinari
{And Death SPEAKS THIS WAY, the Luggage gets your laundry done}
Come and join Rincewind the wizzard and me.

<chorus>

So, friends, do the tour by opening up a book or two
Visit the Discworld by Terry OBE
{If it don't raise a laugh I can recommend a decent shrink}
Come and join Rincewind the wizzard and me.

<chorus>
fade...... 

well it scans when I sing it
