Richardson and The Guess Who had many more hits in the next few years (including the US and Canadian #1 single "American Woman"), and as Richardson's reputation as a producer grew, so did his list of famous clients. From the early 1970s on, Richardson produced some of the biggest selling records of the era: Alice Cooper "Love It to Death", The Irish Rovers' #1 hit "Wasn't That A Party", Bob Seger's "Night Moves", Badfinger, Moxy, Poco, Max Webster and many others. This was in addition to the hits he was producing for The Guess Who, who were for a time (1970) the best selling rock group in the world. From 1984 to 86, Richardson was the music producer for the television show, "Party With The Rovers" (The Irish Rovers) for Global TV in association with Ulster TV in Ireland. Later, Richardson decided on another career change and became a Professor in the Music Industry Arts (MIA) program at Fanshawe College in London, Ontario, until he retired from teaching in 2007. In 1998, Richardson was awarded the Special Achievement Award at the SOCAN Awards in Toronto. The non-profit Jack Richardson Music Awards, started in 2005, are named in his honour and given to up-and-coming musical acts and artists from London in a variety of categories. When Jack Richardson died at the age of 81, The Guess Who frontman Burton Cummings paid tribute on his blog by writing: "He was a great friend... bright, talented and funny. He taught me infinite amounts of about producing and arranging." Among Richardson's producer credits are the following:
