What’s a Labor Day weekend without Jerry Lewis and his “kids” raising money with a painful-to-watch, never-ending TV telethon? This Monday, for the second year in a row, KXAS-TV (Channel 5) will broadcast an abridged version of the MDA extravaganza. They’ll sign on with the telethon at 5 a.m. that day, then cut away for a golf tourney at 1 p.m. before coming back for the final hour around 5. They’ve got to run the golf–network’s orders–and figure nobody watches the all-night portion anyway (Jerry actually kicks the thing off from Vegas on Sunday evening). Promised on the bill this year: comedian Bob Zany (huh?) and singer Billy Gilman (ditto). Charo’s not appearing, but you can always hope for one of Jerry’s cringe-worthy gaffes.
