Lars-Göran Andersson is/was a student of Tomita sensei, who as already mentioned came here in 1969. Of course the saitosensei.com website doesn't mention Tomita.
Btw, on which page of that website do you find the text on Andersson? You can probably right click and find the direct url, or just tell which way I go to find it.
The webpages are arranged according to the era, click on "1970". Both Andersson sensei and Tomita sensei were tagged in a photo taken with Saito shihan in 1972. In another photo circa 1975-1976 taken in a seminar in Sweden, Andersson sensei was a uke to Saito shihan.
