The Royal Marines School of Music has taken to the streets of Portsmouth as part of a flash mob!
Members of the public were treated to an hour-long display of music.
The idea behind the stunt is to promote the School of Music’s major concert at Portsmouth Guildhall this summer.
After the initial 15 weeks of military training, Royal Marines are able to join the music school and start a specialist qualification, studying music.
Once they have finished their course they can join the Royal Marines Band Service.
Their role is then to provide military bands, orchestras and dance bands for state occasions, major national and service events and for ship and shore ceremonial and social functions.
Major Pete Curtis, the Director of Music Training at the Royal Marine School of Music lead the flash mob:
"They are hiding around the corner at the moment, but all of a sudden a 28 piece band, heading down through, playing some famous marches, just showing them what we are all about."
The marching parade certainly gathered a lot of attention and crowds of shoppers stopped to watch the Royal Marines go by.
The flash mob ended with a beating retreat ceremony.
