Lesley,
I've just had a quick look at bar-based lyrics and I cannot quickly see a way to add lyrics for multiple verses.
While I'm studying this in more depth, what you could do is to unfold the song into a single 'once through' format. The command for this is under "Edit | Song Form | Unfold". Then set the number of choruses to "1".
This will lay the song out linearly exactly as you hear BIAB play with the choruses set to 3. I always lay my songs out in a 'once through' linear mode.
NOTE: Before you start playing with things like the above, save your song with a new name so that you can always return to the original if need be.
Regards,
Noel
