"And I Love You So" is a popular song written by Don McLean and released on his 1970 debut album, Tapestry. The song has been recorded by many artists in the years since McLean's original version, and it was a 1973 hit for singer Perry Como on his album of the same name, And I Love You So.

Como's version of the song reached number 29 on the Billboard Hot 100 chart, the last of his many popular recordings to reach the Top 40. It also spent one week at number one on the easy listening chart in 1973. In Britain, the record reached number three on the UK Singles Chart in 1973 on RCA Records and remained on the chart for 31 weeks (longer than any other of his hits in the UK).

And I love you so,
The people ask me how,
How I've lived 'till now,
I tell them I don't know!

I guess they understand,
How lonely life has been,
But life began again,
The day you took my hand!

And yes, I know,
How lonely life can be,
The shadows follow me,
And the night won't set me free!

But I don't let
The evening get me down,
Now that you're around,
Me!

And you love me too,
Your thoughts are just for me,
You set my spirit free,
I'm happy that you do!

The book of life is brief,
And once a page is read,
All but love is dead,
That is my belief!

And yes, I know,
How lonely life can be,
The shadows follow me,
And the night won't set me free!

But I don't let
The evening get me down,
Now that you're around,
Me!
