Soul and R&B singer/songwriter and pianist Doris Troy is perhaps best known for her hit “Just One Look” and as a session singer after she relocated to Britain in 1969.
Her popularity in Britain prompted her first tour in the summer of 1965. It isn’t clear who backed on these dates so we’d welcome any further information in the comments below.

This isn’t a complete list

For this second British tour, promoter Roy Tempest used northwest London group Bluesology who featured a very young Elton John known as Reg Dwight at the time to back Doris Troy. It’s not clear whether Bluesology backed her on all the gigs, so we’d welcome any further information on this.
At the time, Bluesology comprised Stu Brown (guitar/vocals); Reg Dwight (keyboards/vocals); Rex Bishop (bass); Pat Higgs (trumpet); Dave Murphy (sax); and Mick Inkpen (drums)
