Hi Aisling and Ejb, thanks for your help!
Yes, I remember the 1983 concert (the first pic is taken from it), I have it but the problem is that I couldn't find the original dvd anywhere.
The last two pics could be from the same video, but I'm not sure. In fact, she has a different hair style in them, specially in the second pic I posted above. Unluckily, I don't remember the link of the site where I found them. I have sooo many FM links that it's almost impossible for me to find it...
If I'll be lucky enough to find it again, I will post it here. Thanks again for your answers!
