A Singapore night club called "LOX" is using Prince love symbol. You can visit them at http://www.club-lox.com
I've sent an email to know why they use the symbol and what is the relationship with Prince, they've answered that it is not Prince symbol, but however they use to play Prince - George Clinton and further groovy music.
So if one day you come here to visit Singapore, don't miss it, it's on CLARKE QUAY ( very famous here to dance, drink,... ).

[Well, I guess it isn't EXACTLY the Prince symbol, but damn it's close... If I were da man, my lawyer'd be sending a letter -Ben]
