From that worthy tombe "THE GOON SHOW COMPANION", A History and
Goonography, Written and compiled by ROGER WILMUT (a book well worth
buying :-) :
"Before the next series started, the Goons made two digressions from
their normal style of programme. The first was a 'merger' with another
successful comedy show, 'Educating Archie', which starred the
ventriloquist Peter Brough and his schoolboy dummy Archie Andrews.
'Educating Archie' was not a particularly good programme, but it is of
interest today because of the number of famous comedians who played
opposite Archie at the start of their careers-Max Bygraves, Harry
Secombe and Tony Hancock, among others. The series was being written
in 1954 by Eric Sykes, whom Milligan knew but with whom he had never
collaborated. The two decided to write a programme combining the two
shows. 'Archie in Goonland', produced by Roy Speer, was pre-recorded
on May 6, 1954 and broadcast on June 11. According to Radio Times,
'Peter Brough and Archie Andrews enter Goonland via a mousehole and
are immediately involved in a fantastic adventure involving the
destruction of London-and mice!' Unfortunately no recording has
survived of this show, and the BBC's script has gone absent without
leave, but judging by a listener's letter in Radio Times, the two sets
of characters failed to mix. The idea of combining the Goons with
another comedy programme was not tried again. The most interesting
result was that Eric Sykes joined Milligan in writing most of the next
series of Goon Shows."
