The best way of searching on 45worlds/cat etc is to make sure your search parameters are neat but broad.

So for instances there are hundreds of examples of artistes with and without "THE" & in the example of Elephants Memory there are also a lot with and without an apostrophe.

The way to make your life easier in this case is for example
Goto the vinyl album home page type in ELEPHANT (no S) and select ARTIST and this will return 13 different variations of artistes including all 13 albums by "EM..." pls EM with John Lennon + Yoko Ono etc.
