In the UK we now have Rockin' Deep Purple. Cannot see any difference between this and 'Amistad'. RDP may be slightly shorter, it could have been given a dwarfing agent.
Also the Skyscraper series (which we don't have) is remarkably similar to the 'Wish' series. Should this turn out to be the same, then the Australian charity will not receive the Royalties. I really hope that I am wrong.
