"Waltzing Matilda": An Australian Folk Song

On my college days, I used to take various subjects. I love taking notes and collecting handouts distributed by professors in each class I took. As a result, now I have a heap of paper sheets, each full of my handwriting and lecture materials. This morning somehow I happened to have a sudden urge to inspect that pile of paper and I found a song's lyrics originated from the land downunder, Australia. My professor teaching Australian Studies subject gave me this years ago and I thought it would be fun for you to know this song. But sorry in advance, I totally forgot how to sing it but if you really want to know how to sing it, try googling and scouring the web or try searching on Youtube.com. Perhaps that might be of help.
