That's hard to believe as Brandy was indeed a legit hit that all rock fans should like. And it's not a song that's steeped in Americana...like John Mellencamp or Bruce Springsteen might sing that people in England or Ireland wouldn't be able to relate to because they're not from the US. It seems like a song that would carry over to other Western countries.
Plus, the whole "sailor at sea "thing is pertinent to the countries of the UK. So yeah...that is strange it didn't catch on over there.
Don't forget we have never had rock radio, which I assume is taken for granted in the US. If my memory serves me correctly, Foreigner had two hit singles and Journey had one in the UK. Kansas had none. Yes only had one hit single here. Gary Wright's Dream Weaver stuff meant nothing here. We did have rock music programmes: early John Peel, Tommy Vance, and Alan Freeman (an Aussie ex-pat, who was brilliant), but these were glimmering lights in the darkness. There was also Radio Luxembourg 208 in continental Europe, so the broadcast quality was awful. The cliches about listening to the radio late at night under the sheets are absolutely true.
We had some rock music in the singles charts, from the late sixties to early seventies, like The Kinks, Curved Air, Alice Cooper, Hawkwind, Mott the Hoople, Roxy Music, Status Quo, Deep Purple, Golden Earring, Manfred Mann's Earth Band. Looking back, it is hard to believe we even had these. Our singles charts have always been dominated by the lowest common denominator. Currently, it is too awful to describe.
