Former presenter Joe O'Shea shocked viewers when he made an unexpected appearance on RTÉ's Seoige Show last Monday.

After weeks of reading about sisters Gráinne and Síle, it was a reminder of the good old days. Around the country grannies' hearts missed a beat.

However, O'Shea wasn't a guest on the show. It was the result of RTÉ playing an old insert. He told me, "I got a few calls alright. It was pretty confusing when people say they saw me back on the show. It's a pity I'm not getting paid for it!"

O'Shea's fans might not even recognise him these days as he's grown a moustache. Not to escape his TV past, but to raise money for Action Prostate Cancer. More information from www.movember.com.
