If you were to play/introduce your song over here in the UK there would be no negative connotations associated with your title. To change a title an account of possible negative associations could set a dangerous precedent especially in our global community. Imagine if your song had been written in Britain & played here for a while - would the title then be changed if the song was taken over to Canada/US?

I'm sure there are hundreds of songs the have entirely innocent titles/lines in one country that could be taken as offensive or misunderstood in others?

Keep your title as it is & use the title as an opportunity to have an interesting intro. to your song when you play it.
