There are, or at least were. If I'm counting correctly, I have 15 different Shanklin CDs, 5 wonderful CDs by the other, earlier 'Paul' of Rush fame, Silhan, plus Silhan's first album which only came out on casette tape. Not all of their songs made it on Rush and they weren't his only sources, but they were the two largest. Silhan sadly passed away 3 years ago at a mere 66. Shanklin no longer sells his from his website. Amazon lists some of them.
