Scan Tester’s No. 1
Nothing whatsoever do with hospital equipment or IT kit (as you might suppose) but from the anglo-concertina playing of Lewis (Scan) Tester (1887-1972) of Horsted Keynes, Sussex, England.

His two polkas (called No.1 and No.2) are always taken together and in that order (hence the numeric tag).
