Here’s the “favorite song” from Please Please Me I alluded to yesterday. There’s something so simple and lovely about this tune, which you can say about so many great Beatles songs. And I love the use of the intro before the main melody kicks in… similar to Lennon’s opening to ‘If I Fell.’
George Harrison handled lead vocals on this one. Normally George sang only on the tracks he wrote (about two per album, starting with the band’s second release) but he also handled several of the covers (‘Devil in Her Heart’ is a standout among that group) and occasionally, as in the case of today’s song, John and Paul let him take the lead on one of their compositions.
While I think John had without question the best voice in the band (and one of the best pop voices in history), I like George as a singer. His vocals are a big part of the appeal of such songs as ‘While My Guitar Gently Weeps,’ ‘I Need You,’ ‘Something’ and ‘Here Comes the Sun,’ to name just a few. ‘Do You Want to Know a Secret’ is no exception.
You’ll never know how much I really care.
Listen,
Do you want to know a secret?,
Do you promise not to tell?, whoa oh, oh.
Closer,
Let me whisper in your ear,
Say the words you long to hear,
I’m in love with you.
Listen,
Do you want to know a secret?,
Do you promise not to tell?, whoa oh, oh.
Closer,
Let me whisper in your ear,
Say the words you long to hear,
I’m in love with you.
I’ve known the secret for a week or two,
Nobody knows, just we two.
Listen,
Do you want to know a secret?,
Do you promise not to tell?, whoa oh, oh.
Closer,
Let me whisper in your ear,
Say the words you long to hear,
I’m in love with you.
Meet Me In Montauk 
Simple, lovely song.
Interesting that you feel John has the best voice in the band. I think Paul was generally considered the stronger singer, though I prefer John’s voice.
This is a wonderful song and shows the Lennon/McCartney song writing talent right off the bat.
