Lyrics to "Bingo"
There was a farmer, had a dog, and Bingo was his name-O!
B-I-N-G-O, B-I-N-G-O, B-I-N-G-O, and Bingo was his name-O!
The verse is normally sung six times. From the second to the sixth repetition, the participants substitute a successive number of hand-claps for each letter in the word "Bingo" as spelled out in the first. Usually the first letter is replaced (clap-I-N-G-O), then the second, and so on.
