Did a bit of digging. Didn't find much on individual episodes. But a broader picture.
GERALDO RIVERA was on there sometimes...
ABC officially premiered Wide World of Entertainment on January 1st, 1973 following a try-out run from November 21 - Decembet 8, 1972. There were nights, in fact whole weeks, with Cavett or Jack Paar hosting talking shows, but their were also comedy specials

Many individual episodes noted here:

And NOW I remember... MONTY PYTHON was on here too, in infamously cut episodes.
The US networks, never slow to pick up on a trend, wanted a piece of the action too and ABC acquired Python from the BBC's US distribution agent Time-Life Films. When ABC ran the series in its Wide World Of Entertainment slot in October 1975 the Pythons were horrified that the shows had been haphazardly re-edited, thus losing the essential continuity. When ABC refused to stop treating the series in this manner the Pythons, in an unprecedented move, took them to the US courts in a battle for artistic rights. The historic court case ended in mixed fortunes for the Pythons when the judge agreed that their artistic rights had been violated but refused to halt the ABC broadcasts owing to the complex nature of the BBC's US distribution rights. The Pythons then won on appeal which - although too late to stop ABC's original broadcasts - meant that they gained control over subsequent US broadcasting of the programmes.
Somewhere there must be a complete episode guide...???
