The exchange between Ralphie, Al and Steve, reminds me of when Rod Shearman initiated a legal action against Enya for plagiarising Sail Away (which, of course, Rod lost). Jim Mageean went to give evidence in support of Rod, but Enya's counsel asked if he was a career professional singer, and then implied (when Jim said no) that this was because he wasn't good enough to be a professional singer.
