Gary Lewis & the Playboys topped the Billboard Hot 100 the week of February 23, 1965, with ‘This Diamond Ring.’ It was the song’s second straight week at #1.
This was the band’s first single release, and their only one to reach #1. They were one of only two acts to reach the top ten with their first seven singles (the other was The Lovin’ Spoonful).
That success was surely warranted, but it didn’t hurt that Gary Lewis was an early nepo baby, the son of comedian Jerry Lewis. The recording session for this song was funded by Gary’s mom, Patti.
Who wants to buy
This diamond ring?
She took it off her finger now
It doesn’t mean a thing
[Chorus 1]
This diamond ring doesn’t shine for me anymore
And this diamond ring doesn’t mean what it did before
So, if you’ve got someone whose love is true
Let it shine for you
[Verse 2]
This stone is genuine
Like love should be
And if your baby’s truer than
My baby was to me
[Chorus 2]
This diamond ring can be something beautiful
And this diamond ring can be dreams that are coming true
And then your heart won’t have to break like mine did
If there’s love behind it
[Chorus 2]
This diamond ring can mean something beautiful
And this diamond ring can be dreams that are coming true
And then your heart won’t have to break like mine did
If there’s love behind it
[Chorus 1]
This diamond ring doesn’t shine for me anymore
And this diamond ring doesn’t mean what it did before
So if you’ve got someone whose love is true
Let it shine for you
[Outro]
This diamond ring doesn’t shine for me anymore
And this diamond ring doesn’t mean what it did before
So, if you’ve got someone whose love is true

I never knew that Gary Lewis was Jerry Lewis’ son.
This song sounds vaguely familiar. Maybe because I was getting married that year??
