I remember seeing a few episodes of Mospeada at a con, the year before Robotech was aired (we only got half of the last series around here, for some reason), and quite liked it. Back in the days when "Carl Macek" was synonymous with "chainsaw editing". I also remember the original English pilot for Robotech, which had (terrible) lyrics to the theme song. They aired it at that same convention.
That was the one thing that bothered me about fans of my generation is they ragged on Carl mercilessly. He actually did a great deal to make anime popular in the US (people forget his work founding Streamline Video). Some rather vocal idjits celebrated when he died a few years ago, which shows you how bad fandom can be at times.
As for me, I'm still a fan of Robotech (though I prefer The Masters War as shown by my avatar, followed by The New Generation with The Macross Saga dead last). Often times people will say 'Just watch Macross and you'll love it", to which I reply "I've watched all but Delta (which I saw the first episode and decided it wasn't for me), including the entirety of Macross 7 (blech) and Macross Frontier (which was nicely animated, but the story not so great IMHO).
As for the HG dub version of Macross, the opening sounds like someone trying to imitate old Blue Eyes Frank Sinatra..

The only good thing about being a Robotech fan now is the works done by fans of the series (since the IP owners are jackholes) like Robotech: Visions (a Facebook web comic series).
