I think I asked this before to deafening silence. Does anyone remember a visual for a Bowie track with Bowie, (or a Bowie alike) seeing Angie (or an Angie alike) off on a departing steam train? No idea which track but I seem to remember it being on TOTP?
I'm going to research briefly.
Eschewing the 69 Space Oddity release, it would have to come in the 72-75 period, right? Bowie's next hit single after 69 was in 1972.
If it was a Caravel film - as all Bowie's own promo films are accounted for it would have to have been transmitted sometime between 1972 and the last Caravel (which appears to be 'My Boy', Elvis, which is extant and was last shown January 1975).
Ergo, the singles in that period were:-
Starman - no Caravel made
John I'm Only Dancing - Caravel Film exists
the Jean Genie - artist promo shown and exists
Drive-In Saturday - Caravel Film missing, but a rough description involving a couple, a car, and a 'video machine' is known
Life on Mars - BBC film shown and exists
the Laughing Gnome - Caravel Film exists
Sorrow - no Caravel Film made
Rebel Rebel - Pans People dance (exists) no Caravel Film made
Rock and Roll Suicide - song not transmitted
Diamond Dogs - song not transmitted
Knock on Wood -Caravel Film exists
This doesn't look great,
but I am NOT dissing your memory here.It was only a few wee years ago that we had no paperwork or anything except a few viewers memories about the lost Drive-In Saturday Caravel - and after my visit to BBC Caversham it transpired that the PasB for 19/04/1973 edition was lost.
In fact, the recent discovery of the Xmas Day 1967 TOTP audio shows the programme had Traffic on it - which is not listed on the 'Popscene' database (the 'go-to' for TOTP information)
It wasn't even known that a BBC Film was made for the Big O's 'It's Over' (in Stratford Upon Avon) by contemporary TV historians until last month.
Your memory may well be right. I am not discounting this possibility of an unlogged or forgotten and disregarded Bowie Caravel Film being shown.
It's just I can't prove there was one right now.
