This theme will be kind of a collection set, each set is about the same size and features a band with instruments.
-Barber shop quartet.
Four clickies in the familiar barbershop attire. Each with a straw hat and a walking stick, maybe a few instruments as well.
-Rockband.
Four clickies dressed like a 70's rockband with a drum, two different electric guitars and a singer.
-Classical.
Four clickies dressed in formal wear. Instruments are a violin, Bass, tuba and a harp.
-Piano.
Smaller set with a single clicky and a beautifull piano wing. Comes with a clicky dressed in 18th century style with powdered wig and impressive clothes.
A tribute to the classical composers while keeping the clicky generic enough to not look like any particular composer.
-Blues.
A blues band dressed in formal wear with hats and possibly sunglasses.
Included instruments are a saxophone, harmonica, guitar and an old style microphone for a lady singer.
-Country.
four hillbilly clickies with a violin, banjo, guitar and microphone. (a jar could be an accesoire;) )
-Marching band.
Four clickies in marching band uniforms. Includes a drum carried before the clickies chest at a strap with drumsticks, a trumpet, tuba and a pole for the leading clickie.
More suggestions are of course welcome.
Seems to me that sets like this could easily be bought multible times to create a huge orchestra.
