Two very good singing groups that are likely not top of mind have a connection. The 1970s duo Seals and Crofts has the greater notoriety, but England Dan and John Ford Coley had some hit records later in the decade as well. The connection is Jimmy Seals and (England) Dan Seals are brothers.
If you listen carefully, you can hear the vocal resemblance. Seals and Croft hit it big with “Summer Breeze,” but also had several other hits “Get Closer,” “We may never pass this way again,” and “You’re the love,” to name a few. The following lyric is from the chorus of “Summer Breeze.”
“Summer breeze, makes me feel fine, blowing through the jasmine in my mind”
From “Get Closer,” here is the straightforward chorus:
“Darlin’ if you want me to be closer to you, get closer to me
Darlin’ if you want me to be closer to you, get closer to me
Darlin’ if you want me to love, love only you, then love only me
Darlin’ if you want me to see, see only you, then see only me”
While “Summer Breeze” is more whimsical, “Get Closer” is more direct – the singers are not looking for unrequited love. I am committed to you, but I need you to be committed to me,
England Dan and John Ford Coley are remembered for a couple of big hits “I’d really love to see you tonight,” “Nights are forever without you,” and “Love is the answer.” The last song makes you question which of the two duos is singing it. Here are a few of its lyrics:
“Name your price
A ticket to paradise
I can’t stay here any more
And I’ve looked high and low
I’ve been from shore to shore to shore
If there’s a short cut I’d have found it
But there’s no easy way around it
Light of the world, shine on me
Love is the answer
Shine on us all, set us free
Love is the answer”
The latter duo was arguably more pop oriented than Seals and Crofts, but it does not mean their songs were not good. I encourage you to visit or revisit their songs. And, I wish a nice summer breeze for all of us.

Note to Readers: I did not intend to slight the efforts of Dash Crofts and John Ford Coley. Seals and Crofts also had hits in “Diamond Girl” and “We may never pass this way again.”
Coley was a prolific songwriter before and after his partnership with Dan Seals. I saw him later in his career on “Live at the Bluebird Cafe” where songwriters perform their work in Nashville.
