What ever happened to...

In bed last night, I was thinking about how Jo Anna could explain that, although there's no hyphen, she has two first names.

The analogy I thought of was of a 'double A side' single. But since CD singles became the main selling medium for singles, do these still exist? How do you have a 'double A side' CD single anyway? Issue them with different first tracks? (And did cassette singles of 'double A side' singles play differently on the different sides?)

Are they as doomed as the memory that, to name just two UK number ones, Mull of Kintyre and The Model, were really 'double A sides' (and that the forgotten side was better in both cases?)

(no subject)

What resouces exist in London for people with XXY chromosomes (often called Klinefelter Syndrome, although that only affects some XXY men) ?

Given the numbers involved, I'd expect there to be something, but...
