Bruno Mars - Leave The Door Open

I know not everyone here is into current music, but the sound, production and vocals make this sound like I am listening to a 1970's song. Bruno Mars sort of had that retro sound going on Treasure back in 2013, but this just is on another level.

I usually never make a recommendation on what song to listen to as this is not a like/dislike board but every so often someone manages to capture the sound long gone from today's music and it makes my ears rejoice.

They performed the song at the recent Grammy Awards and
I have been playing it over and over since. It's
currently a big R&B chart song.

Happy to see it released as a CD single (two actually, the
latter with the live Grammy performance). Limited editions,
alas, and they're already getting expensive.

And I was just thinking finally a song that fades! ;)

I see this song has just moved up to #1 on the
Hot 100 chart. I still have yet to hear either
version, but I was just wondering which of the
two would be considered the "Hit" version -
the Studio or Live Version? Is the Live
Version getting airplay at all? If a CD Single
was released for it, I imagine it must be
getting some amount of airplay.
