I am useless with a mouth organ / harmonica; really must put some effort into learning to play. However, for our ukulele jams, at the Rover Club twice a month, some brave souls do sometimes play our instrumental breaks; even if only a kazoo.
I have invested in a harmonica holder and kazoo to add another voice to those breaks:-
Great for blues especially, and singing thru it gives a great effect. Can't wait for tonight to show (it) off to the guys.
Don't worry, videos will be appearing asap ....
