In 1873, Grossmith and his father began joint tours of humorous recitations and comic sketches at literary institutes and public halls, to church groups and to branches of the YMCA all over England and even in Scotland and Wales. Young Grossmith's sketches at this time included "The Puddleton Penny Readings", "Our Choral Society" and "In the Stalls". They toured almost constantly for the following three years, but they returned to see their families in London on weekends. Around this time, he met and became firm friends with Fred Sullivan, and afterwards, he met Sullivan's brother Arthur. Through Arthur Cecil, Sullivan, and some of their friends, Grossmith began to be invited to entertain at private "society" parties, which he continued to do throughout his career. Later, these parties would often occur late in the evening after Grossmith performed at the Savoy Theatre. In 1876, he collaborated with Florence Marryat, the author and reciter, on "Entre Nous". This piece consisted of a series of piano sketches, alternating with scenes and costumed recitations, including a two-person "satirical musical sketch", really a short comic opera, called "Cups and Saucers", which they then toured. Grossmith also took a number of engagements, including recitals at private homes. In 1877, Lionel Brough introduced another popular Grossmith song, "The Muddle Puddle Junction Porter". By then, Grossmith had become friendly with many in the music and theatre establishments, including Arthur Sullivan and impresario Richard D'Oyly Carte; and Grossmith had the opportunity to perform in Gilbert and Sullivan's "Trial by Jury" and other Sullivan works at charity benefits.
