There's a song I sing which I picked up years ago but I don't know it's composer/band/history etc. It's called (I think) "Sunday Blues" and COULD be Australian. It's a swamp-rock style song in the vein of Honky Tonk Woman. The first verse is:-

"She looked bad but she looked better last night
Her hair was pretty and her eyes didn't look such a fright
And you'd like to run from the things that you done last night
But the Sunday Blues don't matter on a Saturday night."

...and so on for two more verses.

Anyone help?
