The Captain General - The Band of HM Royal Marines

Thursday 2nd November 2023 saw The Band of HM Royal Marines play a set for Edinburgh Poppy Day 2023 in St Andrews Square, Edinburgh.
The Band is wearing the No 3A General Duty Dress "Half Lovats" Uniform, with raincoats. The Uniform in General is used for rehearsals or general day-to-day duties. It's very interesting to see it out on Parade.
This tune, my learned friend youtube's ContentID system kindly informs me is "The Captain General"
