Secombe met Michael Bentine at the Windmill Theatre, and was introduced to Peter Sellers by his agent Jimmy Grafton. Both Milligan and Sellers credited him with keeping the act on the bill when club owners had wanted to sack them. Together with Spike Milligan, the four wrote a comedy radio script, and "Those Crazy People" was commissioned and first broadcast on 28 May 1951. Produced by Dennis Main Wilson, this would soon become "The Goon Show" and the show remained on the air until 1960. Secombe mainly played Neddie Seagoon, around whom the show's absurd plots developed. In 1955, whilst appearing on "The Goon Show", Secombe was approached by the BBC to step in at short notice to take the lead in the radio comedy "Hancock's Half Hour". The star of the show, Tony Hancock, had decided to take an unannounced break abroad the day before the live airing of the second season. Secombe appeared in the lead for the first three episodes and had a guest role in the fourth after Hancock's return. All four episodes are lost, but following the discovery of the original scripts the episodes were rerecorded in 2017, with Andrew Secombe performing the role held by his then late father.
