I have an LP with more than one groove on each side - I haven't checked it 
for a long time, can't remember how many, but probably six. It's a 
commentary on a horse race, with a different horse winning on each track - 
it's for gamblers to play and bet on at home. As they say, one born every 
minute.

I think I still have a similar 78 somewhere, but it had only two grooves per 
side.

Best wishes
