Her Majesty the Queen had a surprise Christmas hit with the song "Easy Tiger" in 1952, although this record has sadly been forgotten. I found a copy of it in a vintage music store last Easter and plan to release a garage re-mix version next Monday. I at least guarantee that it will be better than "Mysterious Girl".
Sergei Prokofiev taught sewing, until he discovered how to compose music whilst humming along to very boring silent movies during the First World War, when there was a shortage of cinema pianists in Russia.
