Goodbye Again came up elsewhere and it would seem that the conclusions here are wrong.
The last of the four shows (UK4) to be made in the UK was shown as the first of the Kraft Music Hall. A company in the US
has resale rights and some screengrabs of Anne Bancroft and Mel Torme which, was demonstrated with screengrabs from the b/w UK4, match. A trawl of the newspapers comes up with a clipping from the Daily Mirror, 12 Jul 1969, that states the US had already seen the forthcoming edition of Goodbye Again, and sketches include a send up of 'The Graduate, and another with two insurance salesmen who barge in, rather like two mad rapists, asking 'Are you fully insured?' So if KRAFT1 and UK4 are the same, this means KRAFT2 was made from UK1-3, and may mean the RX of UK4 in the KAL guide is wrong. Scouring the web gives a TX on NBC of 30 April 1969 and in 'Anne Bancroft: A Life (pp166) is states: 'Anne took a break from accepting any work during the first half of 1969 - with one notable exception. She flew to London in April to appear on an episode of NBC's variety show Kraft Music Hall hosted by the British comedians Peter Cook and Dudley Moore. She sang "Limehouse Blues" and "Scarborough Fair," and Mel Torme provided a medley of love songs. The British satirists performed send-ups of two popular movies, the modern-day horror film Rosemary's Baby and, yes, The Graduate.'
The Middlesex Country Times reported on Friday 2 May, 1969 that: 'Students from Ealing Technical College took part in the filming of the Peter Cook and Dudley Moore Television show last Wednesday and Thursday [24/25 April]. About 90 went to Elstree Studios to be filmed for the A.T.V. show, which features guest stars Mel Torme and Ann Bancroft'
This would suggest that there was a typo on the paperwork for the month in the RX date, but it doesn't explain why colour was recorded especially for the US for the first three shows, but nothing was done about them until after the 4th show was recorded a year later and then transmitted in the US before the UK. The lukewarm/bad UK press reception of the first three may have had something to do with it.
