Ok thanks Noel, I took a look at that video - it did help in that I did manage to get lyrics in using it (bar by bar). Ive bookmarked it for further reference on other matters that without doubt will arise. (e.g. now that I've got the lyrics in I've spend 40 minutes trying to get the lyrics to increase in size in the lead sheet. Nothing I do in the lead sheet / notation windows - including the options window which has options that appear to be for use with formatting the lead sheet seem to have any affect whatsoever. I can cause change on other elements in the lead sheet (font on other elements of the page) but not the lyrics. They're so small as to be almost unreadable.
This program (BIAB) appears to have a ton of features but coming to grips with it is like pulling teeth...
