John Liptrot Hatton (12 October 1809 – 10 September 1886) was an English musical composer, conductor, pianist, accompanist and singer.
Hatton was born in Liverpool to a musical family, for both his father John and grandfather were violinists. Although largely self-taught as a musician, he became a pupil of Michael Maybrick (uncle of the singer and composer Stephen Adams), who was also the teacher of Charles Santley's father, and also studied in the academy of a Mr. Molyneux. By the age of 16 he had become organist in the churches of Woolton and Childwall and at the Roman Catholic church in Liverpool. (Auditioning for Woolton, he played a voluntary upon the street-song "All round my Hat", hinting at his own name.) A man of many-sided talents and a broad humour attending them, he appeared as an actor on the Liverpool stage. Subsequently he found his way to London as a member of Macready's company at Drury Lane, appearing in a cast led by Macready and Kean in Shakespeare's Othello in December 1832. Santley tells that Hatton took the part of Joe Blueskin (who has the song "Jolly Nose") in the play of Jack Sheppard when it was mounted independently at the Liver Theatre (the 'Little Liver') in Liverpool, simultaneously with the London production (of 1839) in which Paul Bedford took the same role: Hatton scored so great a success that the London production fell flat when it came to Liverpool. Meanwhile he was making his mark as a musician: in 1835 Thomas Attwood wrote to Mendelssohn, "We have recently had a new establishment here which is called 'The Society of British Musicians', in the hope of bringing forward native talent... I, however, wish you would look at your cloak, or great-coat, lest you should have had a bit cut out of it: for there is a young man of the name of Hatton, who seems to have got a little bit of it, indeed he seems to assimilate to your style without plagiary more than anyone I have met with."
In the winter season of 1842–43 he obtained an appointment directing the choruses in the English opera series at the Theatre Royal, Drury Lane, and in February 1843 his own first operetta, Queen of the Thames, or, The Anglers (libretto by Edward Fitzball), obtained a successful run of six performances. This included the madrigal "The merry bridal bells", sung by Miss Romer, Mr H Phillips and Mr Allen.Josef Staudigl, the eminent German bass, was a member of the company: at his suggestion Hatton wrote a more ambitious work, Pascal Bruno, again to a text by Fitzball. Hatton and Staudigl presented this in Vienna in October 1844, as a benefit for Staudigl in the principal part. It had a mixed reception, and was not presented in London, but the 'Revenge' song – the only part to be published – was made very popular in England by Staudigl. Fitzball, finding that his text had been presented, in German, without his consent, the playbill naming 'Herr Fixball' as the English author, was obliged to accept the situation, but it seems to have ended his association with Hatton. But Vienna greatly admired Hatton's piano playing, especially the fugues of J.S. Bach which he played from memory. While in Vienna he took the opportunity to study counterpoint under Sechter.
