So does Paul Rosen's simple player:

X:1
T:Frère Jacques
M:4/4
L:1/4
K:C
c d e c| c d e c| e f g2| e f g2|
g/2a/2 g/2f/2 e c| g/2a/2 g/2f/2 e c| c G c2| c G c2|

Frère Jacques

(You add ?t=xxxxx to the URL where xxxxx is the URL-encoded ABC code. There are online URL-encoders.)

Michael's web tool will generate the URL for you after you paste the ABC into it.
