I'm not sure if you mean playing with them all attached to you, or recording different tracks. I think of a one man band as a guy having multiple instruments strapped to his body at the same time and playing several simultaneously.

I saw a folk/blues performer in a bar one time who stomped a tambourine for rhythm while playing part of his repertoire. I saw somebody else who played guitar and harmonica and also had a kazoo mounted on the rack beside his harmonica. I had already started learning Dylanesque guitar and harmonica performing, so for a while these guys inspired me to try to add the tambourine and kazoo and play two or three together at a time. However I abandoned the extra two pieces after a while as it just was too distracting and not worth the extra effort
