I don't know, I kind of like that they didn't go into a bunch of drama. Probably better for them as well. Keep good blood between a bunch of guys who had a pretty good run for a while. Robbie isn't around to provide his side of the story. If there was anything possibly unfair about it was the exclusion of any mention of Billy Greer. He's been with them since I think the mid 80s, and could be argued was the reason Walsh was able to hang on vocally for as long as he did. Watch some of the live stuff. If you weren't watching closely, sometimes very closely, you might not realize it was Greer who was taking the heat off of Walsh by singing a lot of the high stuff, Walsh in a sense being the solo vocalist while Greer took Walsh's part during a fair amount of the harmony vocal passages. It gave Walsh a break. It was almost painful to watch Walsh sometimes squeezing out the vocals. Compare that to Walsh's younger days when he would sing seemingly effortlessly, no pained look on his face, no obvious strain on his vocal cords. Watch their appearance on Don Kirshner's Rock Concert TV show, them doing Icarus Borne on wings of steel, Walsh seated, effortless vocal power. Compare that to the same song on the Device Voice Drums concert DVD they released maybe around 2000. Walsh still got it out, but it was obvious it took every ounce of effort. Yeah, it was his job, he had to do it, but it was causing great harm to his vocal capability. The writing was on the wall, his days were numbered. It was good while it lasted, I reckon.
I mean, they could have gone into that as well, yeah? Did he bow out gracefully, was he sort of asked to leave? At this point, does it matter? I first saw them probably 79-80, it was incredible, Walsh's vocal was best as I can explain it like a trumpet. As of that point I don't think I had witnessed anything like it.
Now, I wish them all well, but I wouldn't go see them. Walsh was too much of why I was a Kansas fan. Maybe it is unfair, but Walsh doesn't seem particularly an interesting and/or intelligent guy, but on stage he embodied the lyric content, perhaps particularly on the subject of the American Indian... Cheyenne Anthem, for instance. He used to have a website where there was a question/answer section. Fans, asking questions, his answers often curt. "Love the music, Steve! Saw Kansas the last time you were in (location), are you coming back this way on the next tour?!" His answer, "I don't know, we keep touring. I go where they tell me to go, gotta keep toilet paper in the house." Though adopted, besides the American Indian theme in some of their songs, he looks somewhat native American. That and he would at times wear NA accoutrements on stage, beads, feathers, etc. Someone commented on the positive representation of his "heritage". His response, "I have no heritage." At some point he or someone closed that section of the website. Probably for the best, apparently he couldn't be bothered to be nice to people who still gave a damn and were responsible as fans for whatever wealth and recognition he may have acquired. People who kept toilet paper in his house.
In a nutshell, the documentary in question, would it have added anything of interest to provide Walsh an outlet for that kind of negativity? Like I said, there was probably good reason Robbie acted as MC talking between songs rather than the main voice of the band Walsh back in the day. I don't know, maybe I'm being unfair.
