Susanne,You asked about Paddy Hernon's "By Request" CD. I don't know if you can find it in stores. It is an independent release. It is called "By Request" because Paddy's friends urged him to record some of the songs they heard him do live. He did a wonderful job.
I just ordered 3 more copies recently (yes, I like this CD) via email from Paddy directly. His email address is paddy@tallship.bc.ca. I suggest you email him and work out arrangements to have a CD sent to you.
Paddy is also the skipper of a tallship on which he lives. He has a web site that you can get to by selecting this blue clicky thing.
If you contact Paddy tell him I sent you.
