When The Co-Optimists re-formed in 1930, he rejoined that company, now at the Savoy Theatre, and at the same venue appeared in Savoy Follies in 1931,[52] where he introduced to London audiences the monologue The Lion and Albert.[53][n 6] The monologue was written by Marriott Edgar, who based the story on a news item about a boy who was eaten by a lion in the zoo.[55] In the monologue, Mr. and Mrs. Ramsbottom react in a measured way when their son Albert is swallowed. Neither Edgar nor Holloway was convinced that the piece would succeed, but needing material for an appearance at a Northern Rugby League dinner Holloway decided to perform it.[56] It was well received, and Holloway introduced it into his stage act. Subsequently, Edgar wrote 16 monologues for him.

Holloway was already enjoying some success with the monologue format, with such classics as Sam, Pick Oop Tha' Musket. Edgar asked him if he had heard a story about a couple who had taken their son to the zoo, only to see the lad eaten by a lion. Holloway had indeed heard the story, and shortly afterwards Edgar supplied him with a script. The Lion and Albert became one of Holloway's most popular pieces, one of many he recorded beginning in 1930.[9] The lion of the poem is named "Wallace", which was the name of the first African lion to be bred in Britain, living from 1812 until 1838, and his name became a popular one for lions.[10] Edgar gave the poem the title The Lion and Albert, but some later performances and re-publications used the form Albert and the Lion.

The monologues were designed to be spoken rhythmically with piano accompaniment, which in many cases was also composed by Edgar.[12] The texts were published by Francis, Day & Hunter Ltd. during the 1930s in three collections. All were illustrated by John Hassall, many of whose lively images also became classics. Edgar's compositions were - see https://en.wikipedia.org/wiki/Marriott_Edgar

In 1929, he joined the cast of The Co-Optimists and worked with Stanley Holloway.[9] At the start of the 1930s they went to Hollywood, where Edgar – who had dropped his first name for the professional appellation Marriott Edgar – met his half-brother Edgar Wallace.
