I am a bit disappointed to see no one complaining about Joe's ABC code of 12½ years ago, which obviously was produced from the MIDI by software, misplacing the bar lines. Are black dots a case for a strong detergent?

The same tune with corrected bar lines:

X:1
T:Weela Wallia
M:2/2
Q:1/4=120
K:D
A|"D" A AF2F FA2|A2F F F4|D2F2A2A2|"G" B4 "D" A3\
w:There was an old wo-man who lived in the wood, Wee-la wee-la wall-ia;
A|"A" A AE2E EA2|A2E EE4|"D/F#" A2A3/2 B/2A2F2|"A7" E4 "D" D3|]
w:There was an old wo-man who lived in the wood, Down by the ri-ver Sall-ia.
