I also found my anti-roll bar bushes are knackered (Thanks Gary) but hey hoo that's another job for the list!!
I also have a random noise from the front end. Did your noise sound anything like mine in the videos below?

A mechanic straightened out the cross brace that hit the central beam but the noise came back after a couple of days.

Any ideas about what might be causing this noise?

The sound changes character when I press the clutch pedal. It becomes more muffled.

The noise is present at all speeds. Here is an example while driving slowly in first gear.
