May 1951 on the BBC Home Service. Although he did not perform as much in the early shows, Milligan eventually became a lead performer in almost all of the Goon Show episodes, portraying a wide range of characters including Eccles, Minnie Bannister, Jim Spriggs and the nefarious Count Moriarty. He was also the primary author of most of the scripts, although he co-wrote many scripts with various collaborators, most notably Larry Stephens and Eric Sykes. Most of the early shows were co-written with Stephens (and edited by Jimmy Grafton) but this partnership faltered after Series 3. Milligan wrote most of Series 4 but from Series 5 (coinciding with the birth of the Milligans' second child, Seán) and through most of Series 6, he collaborated with Eric Sykes, a development that grew out of his contemporary business collaboration with Sykes in Associated London Scripts. Milligan and Stephens reunited during Series 6 but towards the end of Series 8 Stephens was sidelined by health problems and Milligan worked briefly with John Antrobus. The Milligan-Stephens partnership was finally ended by Stephens' death from a brain haemorrhage in January 1959; Milligan later downplayed and disparaged Stephens' contributions. The Goon Show was recorded before a studio audience and during the audience warm-up session, Milligan would play the trumpet, while Peter Sellers played on the orchestra's drums. For the first few years the shows were recorded live, direct to 16-inch transcription disc, which required the cast to adhere closely to the script but by Series 4, the BBC had adopted the use of magnetic tape. Milligan eagerly exploited the possibilities the new technology offered—the tapes could be edited, so the cast could now ad-lib freely and tape also enabled the creation of groundbreaking sound effects. Over the first three series, Milligan's demands for increasingly complex sound effects (or "grams", as they were then known) pushed technology and the skills of the BBC engineers to their limits—effects had to be created mechanically (foley) or played back from discs, sometimes requiring the use of four or five turntables running simultaneously. With magnetic tape, these effects could be produced in advance and the BBC engineers were able to create highly complex, tightly edited effects "stings" that would have been very difficult (if not impossible) to perform using foley or disc. In the later years of the series many Goon Show "grams" were produced for the series by members of
