In 1956, he joined London band The Silhouettes. The group relocated to the Windsor/Detroit area where work was more plentiful. It was there, in 1958, that The Silhouettes joined with fellow Londoner Paul "London" Hutchins and became Paul London And The Capers. Hudson primarily played saxophone in the group, and some piano in a style inspired by Johnnie Johnson, but saw his first Lowrey Organ at a show in Detroit and determined that he would get one. The group found moderate success and plenty of work, recording a few songs in Toronto in 1960, changing their name to "...Kapers" with a 'K', recording a few more songs at Chess Studios in Chicago.
