Milligan was no mean jazz trumpet player. When the Goons underran the alloted half-hour the Wallace Greenslade Orchestra (including many jazz players like George Chisholm on trombone) used to jam till the time ran out, often Spike's trumpet was featured.
More musical Goons trivia: Ray Ellington's group, who played the half time music, often included jazz pianist Dick Katz and tv chef Ainsley Harriott's dad.
With the total recall of youth we used to repeat episodes practically word for word in the school playground next day.
Now, of course, it toook me a minute to remember Wally Greenslade's name! All radio comedies of the era seemed to have a musical number half way through (Alma Cogan in Take it from here, the Fraser Hayes Four in the Kenneth Horne shows etc.)
