As the awarding body we cannot comment directly on whether the backing track you have selected is permitted, or suitable for your Learner and their upcoming assessment.
As explained in Examination Regulation 4:
"Backing tracks which include any vocal performance, including backing vocals, are not permitted."
(Examination Regulation 4, Page 14 of the current LAMDA Solo / Duo Musical Theatre Graded Examinations Syllabus with effect from 01 August 2021)
See "Why are backing vocals not permitted on a backing track?" for more information
Backing tracks can be sourced from a range of places. Further information can be found on page 5 of our Musical Theatre Teacher Support Materials.
