That certainly does sound like the string section. A very good gloomy
doomy example of it. In the mellotron.com listening room, it states
string section was introduced to the M400 catalog in 1973 (Ummagumma
dates to 1969).
Presumably, he could've created it himself with overdubs (cello +
violins etc.). Or perhaps someone else has insight that would resolve
the discrepancy.
