Stairway to Heaven - Reggae

I recently listened to the Reggae version of Stairway to Heaven. It’s not too thick in texture. I can hear vocals, keyboard or synthesizer and drums. I have also heard dynamics. There are crescendos in the vocals very often. It sounds like there are a few rit. as well especially in the last minute or so. This piece is syncopated rhythm. I can also tell that the meter is ¾. Listening to the piece I can hear it is adagio, sometimes andante. But I don’t think like that. Sometimes the beat is at a walking pace, and sometimes it’s a bit slower.
