>Two vintage collectors’ items will air this week. Making the first of many comebacks in 1973, Frank Sinatra was in rare form on Of Blues Eyes Is Back (Disney, Sun., April 29, 9 P.M. ET) with guest Gene Kelly. The highlights are superb renditions of “I Get a Kick out of You” and “I’ve Got You Under My Skin.” It’s the first of 13 old Sinatra TV specials the Disney Channel will show over the next two years. The next night CBS offers I Love Lucy: The Very First Show (Mon., April 30, 10 P.M. ET). This is the never-before-seen 34-minute pilot for the classic sitcom with Lucille Ball and Desi Arnaz, fleshed out with later clips and hosted by Lucie Arnaz.
