Tn2020, Discussions shouldn’t be closed. I’ve reopened this one, replaced the deleted title, and restored the signature portion of the original image to the OP. I also moved this to the Beatles forum. Thanks.
Thanks Ballroom. I love it when members come on here for a free opinion, dont like the answer, and try to delete the discussion. We don't charge for opinions, but at the very least, they could leave it so others can learn.
