On November 20 Mick Jagger, Keith Richards and Andrew Oldham gathered at London's Regent Sound Studios to work on demos of the very first Jagger-Richards compositions. These demos were intended as potential sale to other artists and were never released by the Stones themselves. The next day, and also on December 9, the other band members, this time including Stu, joined the Unholy Trinity, and some recordings were made.
Stu plays piano on 'My Only Girl', a song originally intended for singer George Bean, but later re-recorded (with Stu's piano lines intact), after he had changed the melody, by Gene Pitney under the title 'That Girl Belongs To Yesterday'. Pitney's version was released in March 1964 and reached number seven in the charts. This was the first time a Jagger-Richards song had gone top ten in the UK.
