I listened to this song by Jefferson Starship and I can say Jefferson Starship really did a great job on this song and With Your Love has such a laid-back summery vibe to it and it's a really soothing song. How did this song come about?

To me, With Your Love sounds like a rewrite of their previous hit "Miracles". The song structure is similar.

Yes, it has similar chords with Miracles. Good catch.

I like "With Your Love" a little better than "Miracles," both really good though.
