Question

please tell

Answer 1

There's a song called "I Will" by the Beatles, written and sung by Paul McCartney (although the credits say Lennon/McCartney). Here's some of the words:

Who knows how long I've loved you
You know I love you still
Will I wait a lonely life time
If you want me to I will

The link below is a YouTube video of a guy playing "I Will" at his wedding. Is this the song you have in mind?
