The authentic shirts would have said “Frankie Say Relax”, because in British English groups or companies are referred to as plural. It’s really weird to see in print.
Ah yes, the table scene with 16 people and a blue dude that made fun of the Last Supper, which had neither 16 participants nor a blue dude.The local archdiocese tried to act all offended about it and they had to close replies on all their social media accounts within minutes because they got unloaded on.
I have a worn-out “Don’t blame me, I voted for Bill & Opus” shirt somewhere.
