His musical style represented the true spirit of SS to me.
The 2nd muppet movie, The Great Muppet Caper, was scored completely by Raposo. It's worth checking out for the "Couldn't We Ride" segment alone. It was one of the best songs he ever wrote, and it would have easily worked as a SS film segment back in the day. I wish I had a recording of Joe singing the song. There was an old film of his on SS called "Water Baby" that was somewhat similar musically.
