Yes WBHM I am of the age remembering seat back catering. One of my first flights was to Spain on a Monarch 1-11 from Luton with seat back catering. Also all passengers had to be weighed on the scales along with luggage - it was strong head wind and unsure if 1-11 would make it to Malaga without stopping for refuel. One plus point in those days - if I remember correctly - soft drinks and mixers were free, you only paid for alcoholic drinks.
