Blimey Mike that was weird...you must have posted whilst I was still typing mine coz that wasn't there then!!
If you have a mic on your pc/laptop you could make a recording via that (to the person that asked!) or on a camera with a sound recording function and then upload to the pc and convert to an MP3.
Mike if you're putting votes my way vote with errr...actions and get me a backing track then I'll think about it
