Right you are Brink!

I'm here with the info. for Mike!
Mike,"Summer Side Of Life" while a great-great song did not make the national top 40 here in the states,sad to say.
During the week of 9/12/71 through 9/18,the song barely squeezed in at #98 on the Billboard Hot 100. (Sort of insulting when one finds out the #1 song that week was,"Go Away Little Girl" by Donny Osmond!

)
Gord's 6 top 40 hits are as follows (in order from '70 to '78):
If You Could Read My Mind #5 Feb. 1971
Sundown #1 (One week) June 1974
Carefree Highway #10 Nov. 1974
Rainy Day People #26 May 1975
The Wreck Of The Edmund Fitzgerald #2 for 3 weeks (behind Rod Stewart's,"Tonight's The Night".

Nov. 1976
The Circle is Small (etc.) #33 April 1978
Very briefly,Gord's other singles that charted between #41 and 100 and that didn't even chart at all!:
Baby Step Back-#50
Beautiful-#58
Talking In Your Sleep-#64
Race Among The Ruins-#65
Cotton Jenney-#71
(again) Summer Side Of Life-#98
Outside the Hot 100 (known as the "Bubbling Under" Chart:
#101-You Are What I Am ("B" side of next song).
#102-That Same Old Obsession
and #111! - "If I Could". (Released by UA after "..Read My Mind" became a hit.)
There you go Mike!

I reccomend,if you wish to know of other artists Top 40 Hits in America,that you buy a copy of The Billboard Book Of Top 40 Hits (8th Edition.)
The 8th edition just came out this month and all you have to do is go to your nearest bookstore and special order it. I'm getting mine in about a week. Been me. Later!
