The people who are remembering the number as 16 or 160 are both correct. It depended upon which part of the country you were in and which exchange served your line.
In London and a handful of other larger cities the equipment in use in the 1960s/70s waited for the first three digits of a number to be dialed before deciding how to route the call, so all "special" short codes had to be three digits long, and Dial-A-Disc was assigned 160.
In many other towns, however, the switching equipment worked in a slightly different way and it was possible to have a two-digit code which would connect directly to a service. Thus in these places it was generally possible reach Dial-A-Disc with just 16.
The same 16/160 numbers were used to announce cricket scores during test matches.

- That's a pretty definitive answer. Many thanks.
Also, I've found this number. If you dial the first 11 digits, wait for the recorded message and the beep, then dial the next 6, you get through to an original recording of Dial a Disc.
