It's by Ian Campbell of the Ian Campbell Folk Group. ("I just can't wait to collect my cards" is the first line.) It doesn't seem to be in the DT or a previous thread, and I don't think I've got it anywhere (but I'll check). It's only a matter of time before somebody finds it!

It's a real period piece now -- how many people nowadays would jump at the chance of a job for life, so secure that you couldn't easily leave it by choice?
