This is the CD I listen to (and sing along with) in the car on my daily commute.
My favourite is The Wyverary, a fantastic beast in a fantastic song . But I also love Villian's Cat and Hydrogen Burns. (And one of these days I'm going to catch that red dot too!!)
I only "discovered" Cat Faber a few months ago - and then looked at some of the other filk songs I love and found she had written those as well :-)
