´I will` by ´The Beatles`.

Good morning!!!!
Listen to the song: ´I will`. It was created by ´The Beatles` in 1968, before we were born!!!! You can sing along, at the end you should answer this question:

What word is repeated in the song? I give two clues:

1^st _ The word ends in ´l`.

2^nd_ Look at the title of the song.

I will write the answer after Easter…
