The pairing Q I had thought of, but rejected was:
How do you connect East Lynne with the Royal Albert Hall?
Mrs Henry Wood wrote "East Lynne", and Sir Henry Wood inaugurated the Promenade Concerts at (now) the RHA.
Alternatively, use the original venue for the Proms, Queen's Hall, until bombed in 1941, as in "What was Hermann Goering's impact on the Proms"?
