I am so very sad to hear of Anne Byrne's passing. I have been a huge fan of her music for many years. I was lucky to have found most of her albums over the years. I live in California and found a few of her albums in used record shops here but found most in record shops in London when I was visiting there in the 1980's.
I just had to try and find all her albums including the ones where she sang on some of the Abbey Tavern albums.
I'm not sure if I have everything she ever recorded but probably have the majority of albums (all vinyl.)

My sincere condolences to her husband, sons and all her family members
and friends.
What an incredibly talented lady!
