It's amazing that he's managed to get through life without any 'sneaked' photo's of him kissing another man seductively on the lips - so who knows.
Anyway, whether he is or he isn't, matters not a jot to me! As long as he keeps all the grey, permed, blue rinse brigade happy is all that counts - not including me I might add! ;o}
Years ago my mum & auntie dragged me (kicking & screaming) to see him. We had front row seats.
He was wearing tight trousers and all I can say is that he didn't...ahem...seem to have much in the way of a lunchbox.
it's possible to keep lunchboxes out of sight - Prince Albert is said to have had a Prince Albert for this purpose - and Cliff being a gentlemanly sort would probably have done so; while singers otherwise inclined were stuffing giant marrows down their pants.
