Sir Real Jazz is a group of young professional musicians available to play in and around the London area. We offer groups of varying size to suit your needs, from subtle background combos to full blown swinging big band.

Sir Real was started originally as a quartet in September 2005 by Rob Cossins and Chaz Keiderling joined by Mark Johnson and Phil Warrilow-Wilson. The group was soon playing frequent gigs and regular ‘deps’ slowly became regular members and so the decision was made that it would no longer be a quartet but a group with a varied size band depending on the number of players needed.

In 2007 Chaz Keiderling established a handful of new members all based in London. The players are all at a professional level and while some are full time musicians others are persuing an assortment of other passions. Working with the IC where Chaz plays lead Sir Real Jazz are now able to offer a full big band covering all the classic dance numbers.
