When the band moved to Mercury records after leaving Sony Music one of the biggest mysteries has been which singles have actually been released or not, and why there were no physical CD singles available. I'm still none the wiser as to which singles were released or not but the answer to the physical single question seems to have been answered as news stories today (Friday) reported that Mercury Records have announced that they will stop producing physical CD singles as standard.
So, I guess that means that the last (ever?) official Jamiroquai CD single release (at least in the UK) was Runaway in October 2006.
