In 1870, the Lenos appeared in another pantomime by Leno's father, "Jack the Giant Killer; or, Harlequin Grim Gosling, or the Good Fairy Queen of the Golden Pine Grove", in which Leno played the title character and featured in the variety entertainment that preceded the pantomime. Throughout the 1870s, Leno and his parents performed as "The Comic Trio (Mr. & Mrs. Leno and Dan Patrick) In Their Really Funny Entertainments, Songs and Dances". In the family act with his parents and Johnny Danvers, young Leno often took the leading role in such sketches as his stepfather's "The Wicklow Wedding". Another of their sketches was "Torpedo Bill", in which Leno played the title role, an inventor of explosive devices. His parents played a "washerwoman" and a "comic cobbler". This was followed by another sketch, "Pongo the Monkey". Opening at Pullan's Theatre of Varieties in Bradford on 20 May 1878, this burlesque featured Leno as an escaped monkey; it became his favourite sketch of the period.
