I have a couple of books of sheet music for Cliff and The Shadows, most of which show the bass guitar by itself, on a bass clef music staff. I could scan the sheet music and send it to you, if I have any songs that you want. I could also tell you the titles and catalogue numbers of the books, if you wanted to buy the books from amazon.co or eBay.
Kind regards,
Donna
PS: Here is a sample. Page 1 of "Please Don't Tease". Probably not the song you were looking for; just an example.
