Monkey stick

The Mendoza, Mendozer, Money money money Stick, Murrumbidgee River Rattler or Lagerphone is a traditional English percussion instrument, widely used in folk music. The origins of the name are not known but it is believed to stem from an association with one of the many Gypsy, Spanish and Italian buskers who were popular in London in the Victorian era.

This instrument is constructed from a stout pole affixed to a heavy boot at the base (originally the end is believed to have been covered with a rag to give some protection to the pub floor; the boot is probably a more recent addition). Metal "jingles", commonly beer-bottle tops, are fastened at intervals along the shaft; putting a 1" washer in between the tops enhances the quality of the sound. When played on a wooden floor (common in ale-houses), the sound produced is a combination of a bass drum and tambourine. It can also be played with an additional small notched or serrated stick held in the other hand, allowing it to not only be shaken or hammered onto the ground, but also "bowed" to produce a combined clicking and rattling sound.
