Lori Balmer, who recorded a single with the Bee Gees in 1966, moved with her family to England around the start of 1968, and now recorded her second and last single in one session. Both songs were played by the Bee Gees with Bill Shepherd orchestration. They have intriguingly strange lyrics very characteristic of the Bee Gees at this time.

In January 1968, following an invitation from Barry Gibb, she travelled to England with her parents. They stayed with the Gibb family and she began to work on children's TV shows & radio, such as The BBC 1 Club, regularly. The British press dubbed her the"bush baby" and would occasionally appear on the same shows alongside the Bee Gees.. At this time too she soon found herself in the recording studio putting down two new Bee Gee's composed songs "Treacle Brown" and Four Faces West". All backing and production was provided by the Bee Gees (including then members Vince Melouney and Colin Peterson), with Bill Shepherd doing the arrangements. This was duly released on a single on Polydor, however legal problems prevented her from going any further with it. By accounts it seems this record demonstrated a voice more powerful than could be expected from an eleven year old.

In 1971, Lori was signed to Pye Records with Tony Atkins as the producer releasing the single "Here Before The Sun" in 1972. She continued working in the UK as a support to The Marmalade, The Hollies, Johnny Mathis, and various artists in UK and Europe.
