Most artisits from other countries could tell you how important it is to breakthrough in the U.S. If an artist wants to be recognized world-wide,making it in the U.S. is almost a priority. Americans tend to be fussy about their music like kids are fussy about eating vegetables!
In Gord's case,it was most likely at one time very important. That being when he was trying to get his music out thee on UA records and then maybe the his first few years at WB/Reprise.
After releasing all those LPs in the 70s though,I'm sure it wasn't as important,for as we've said on here before,he wouldn't play the "fame-game" that most artists do.
Having some hits here was a good thing but the unfortunate fickleness of the U.S. music scene took away his popularity almost as fast as it had given it to him.
In a strange way,I'm sure it was a great relief to him not to have to put out something every year anymore. That's a lot of work (especially after your label & the folks at radio aren't behind you 100% anymore.) I hear he's still very popular in other countries but,still it would be a sweet victory if Harmony actually sold enough to be on the Billboard Top 200 album chart.

Aurevoir!
