Economic debate: Banks and a balanced economy
Birmingham: What have I learned tonight about the parties' policies on sanitising the banking system and rebalancing the economy so that it is less dependent on the City?
Not a great deal - and, believe me, I was listening intently.
In respect of mood rather than substance, David Cameron was clearer than I had ever heard him on the need to separate retail banking from investment banking - though he did not say whether he would break up the banks in the absence of international agreement.
He was also crystal clear about the imperative of levying a tax on the banks, even if other countries don't.
On these two issues, and you wouldn't believe it from their mutually hostile body language, David Cameron and Nick Clegg aren't that far apart: although the Lib Dems would levy a new 10% tax on banks' profits, whereas the Tories would tax their wholesale borrowings.
Out on something of a limb was Gordon Brown - who defended big banks and also argued that it would be wrong to impose a new tax on banks in the absence of international agreement.
David Cameron also made an intriguing statement about wanting to give the Bank of England the power "to call time on debt in the economy" - which was presumably a nod to so-called macro-prudential policy, or the provision of a new power to the central bank to ration credit in boom years.
There was, however, an outbreak of consensus on the need to promote manufacturing, especially "green" and hi-tech businesses - though I struggled to glean any convincing detail from any of them about how they would achieve this in a meaningful way.
That said, there is a serious division between Brown and Cameron about the taxation of business - on top of their spat about Labour's plan to raise national insurance next year.
Cameron favours cutting the headline rate of corporation tax for all companies, financed by the reduction of assorted tax allowances for them.
Brown characterised that approach as a cut in taxes paid by banks - which Cameron only half disputed.
The prime minister's implicit point is that the removal of corporate tax allowances would hit investing manufacturers disproportionately more.
I suppose on these narrow but important issues I rated the debate as a slightly dull no-score draw - the sort of thing we may experience in the looming Bayern/Inter Champions League Final.
Where's Lionel Messi when we need him?
Update 2355: The coffee has all gone cold. And the Blackberries (except mine) have been put away.
So what's the overall verdict on tonight's performances in the round (and not just on the stuff that relates to my eccentric interests)?
Well, what I would point out is that Gordon Brown's crew was pretty glum as Spin Alley was dismantled until the next election. Team Brown felt that Brown had been too negative.
By contrast, the Tories were cheerful. And the Lib Dems seemed a bit nonplussed.
As for the rampaging press pack, it scored Cameron first, Clegg second and then - a bit in the rear - Brown. The hacks echoed the post-debate polls.
