LOLWTF? Nah, last.fm needs a better system for this type of shit. I just scrolled through 65 (mostly) awesome pictures of Lush, then I see this. This happens very often on last.fm and in music in general - bands with the same names. They could very easily just do something like "Lush (UK)" and then have "Lush (Canada)" and it'd lead you to the respective pages.
