Does anyone remember the Pepsi ad with the guy who played Andy Evol in Agony and Kirk St Moritz in Dear John, I think his name was Peter Blake. The ad showed a not very confident guy asking Petr Blake 'how come you're such a big hit with the girls' To which he launches in to an Elvis type song about how cool and smooth he is. I've been looking on the old ad sites and can't find it anywhere.
I've since managed to check The Guinness Book of Hit Singles and it was actually called " Lipsmackin' Rock'n'Rollin' " and it only reached Number 40 in October 77.
