Well, as the voiceover on the 1960's tv version of Batman used to say, "anything can happen in the next half hour!"
Just after I finished whinging about this blasted cd that I couldn't play, third born came downstairs and told me he'd managed to burn a cd of it on his computer. Now, it's not as simple as that. First I had to get the new disk to play. Eventually I did manage (this from a complete Luddite). So, I now have the whole cd on my iPod.
. . . except to ask why he couldn't do it about six months ago. Ah well, everything comes and all that.
