Joy [2] is the same as the red-headed Joy on the Johnny Rebel site (same face, same tatoos on front). This Joy features on the cover of XXX British Hardcore 18 with Kim Diamond, so Joy [2] should be added to the cast list for XXX British Hardcore 18. She must also be the Joy who shares a scene with Kim in Naughty Shorties 2, so she should be added to the cast list there too.
On the XXX Brits site she is listed as Joy-Licious, but I can't see this name anywhere else.
