Help has arrived. My name is Howard Kleidman (dranot@optonline.net),
and I've been singing this song for a lifetime, with the intro as follows:
          I know a guy named Izzy
          And he's always busy
          Making love to women every night
          Now one of them is Sarah
          And what a holy terror
          She wouldn't give him up without a fight
          When she saw him flirting with the gal who lived next door
          She got hoo-ha so excited that she started in to roar hor-hor
          hor --Whose Izzy Is he (etc,)
