Those Fritz Werner Bach CDs were everything I hoped, the second ten being just as wonderful as the first ten. And the second ten were even cheaper, hardly more than twenty quid at the Bond Street branch of HMV (which is in Oxford Street just across the road from Bond Street tube).

Particularly wonderful is track 2 of Cantata BWV 78, which is on CD 3 of these second ten. This is sung by the lady choristers. Werner, and in particular his harpsichordist, who I see now was Marie-Claire Alain, accompany it with a bounce and a joy that I have never heard before. It has become fashionable these days to talk about Bach writing dance music. I've never really heard this myself, until now.

Googling for "Bach Cantata BWV 78" revealed that this particular Cantata certainly seems to strike a lot of chords with a lot of people, and this second movement especially.

Here, for example, the writer zeroes in on this movement, and helpfully supplies the words, to save me typing them in again, in both German …

Wir eilen mit schwachen, doch emsigen Schritten,
O Jesu, o Meister, zu helfen zu dir!
Du suchest die Kranken und Irrenden treulich.
Ach, höre, wie wir die Stimme erheben, um Hilfe zu bitten!
Es sei uns dein gnädiges Antlitz erfreulich!

… and English.

We hasten with weak [feeble], yet eager footsteps,
Oh Jesus, Oh Master, to seek after your help!
You tirelessly seek out the sick and those who have gone astray.
Oh, hear us, as we, our voices raised, pray for your help!
May your merciful countenance be gracious unto us!

The way Werner and his ladies do this makes it sound as if this is already happening.
