Ollie, same rules apply as those we use to determine using music - the work is copyright and cannot be used without license. Currently the copyright owners will be his estate and/or publishers (depending on how he assigned rights when making the recordings). but it gets trickier: there are also publishing rights and mechanical rights, most likely held by the companies that published the material on video or vinyl or cd
Given that he died in 2008, the copyright in his work will continue for at least 75 years, so you will need to deal with the copyright owners
