(Debuted October 15, 1983, Peaked #20, 16 Weeks on the Chart)
I guess I have to preface this with the fact that I turned 12 in 1984. At the time, I (along with my friends) found the title "Big Log" to be rather funny for purely juvenile reasons. Besides that, there was a friend's older brother, a Led Zeppelin fanatic, who just didn't like the way the song went. Since Robert Plant had been the lead voice of Led Zep, he just found it atrocious that he was willing to do such "soft" material.
Time has passed, and I can listen to the song today without snickering (much) at its title -- which, by the way, is never actually mentioned in the words of the song -- and find it to be a great 1980s single. From the casual guitar to the mellow synthesizer lines, the music suits the mood. Not only has Plant explored his vocal range in the years since, he has also branched out into totally different genres that make this song seem not so "soft" anymore. As for the friend's brother who argued that the voice of Led Zeppelin shouldn't be on this single, I lost track of him 25 years ago. I'd be interested to hear what he had to say about it today.
Actually, he might be pretty favorable with it, too. He was about 18 at the time and life's lessons often have a way of changing our outlook on things. I know my own view of things is a lot different than I saw things back then.
