I don't think it is. We choose a charity each year to do a gig for and one of our close friends had breast cancer, so we decide to choose the Breast Cancer Campaign as the charity to receive the money we raised.
No other reason. The 2 previous years we also chose charities in a similar way, as a response to those we knew.
No offence intended, (or taken,) as I did not suggest or intend to suggest that breast cancer is more of a worthy cause that that of raising money to research prostrate cancer.
Hope that answers your question with regard to us choosing this charity, Peter.
