He agreed with me that if the `tension’ is indeed real then it is far more likely to be a problem with stellar distance measurements than the cosmology.

Second, I am writing a review of all this to be published in Astronomy & Geophysics next year. Watch this space.

Third, this gives me an excuse to include yet again my poll on whether you are worried about the “tension”:
