Table schema:
CREATE TABLE table_name_70 (notes VARCHAR, bronze VARCHAR, gold VARCHAR, year VARCHAR)

Question: What is Notes, when Gold is "Thierry Gueorgiou", when Year is before 2008, and when Bronze is "Valentin Novikov"?
SQL: SELECT notes FROM table_name_70 WHERE gold = "thierry gueorgiou" AND year < 2008 AND bronze = "valentin novikov"
