Anyone who insists on positioning him or herself in front of the television set tonight between 11:30 and 1 a.m. to watch NBC's special, "Friends'" a triptych of inter­views with TelIv Savalas, Lindsay Wagner and Hugh Hefner, has to be so committed to living life vicariousiy as to be beyond the pale of reasonable discussion.

Yet, apparently there are those who will delight at the opportunity to visit a London casino where Savalas insists that London "is a man's city and that makes it good for women": there are those who will enjoy lunching in the French Riviera with Miss Wagner who reveals a desire "to do films that have some substance"; and even those who yearn to take yet another videotaped tour through Hefner's mansion.

The only new thing about "Friends," however, is its in­terviewer-host, Bill Boggs, who introduces the show while bicycling through Cap d'Antibes. Who is this man, this Wonderbread version of Geraldo Rivera? Where did he learn the lingo of the plastic hipster, asking Miss Wagner "How do you deal with some of the problems that face ev­erybody in the loving relationship?"; complimenting Hef­ner for "creating an incredible environment?" More im­portantly, does Boggs own the Mercedes that he drives or does he only lease it?

Those are just a few of the questions which "Friends." a Syd Vinnedge Production produced by Joe Byrne and di­rected by Joel Tator, never really answers.
