This remarkable artistic and historic treasure may be seen in its entirety at the Paley Center for Media, 25 West 52nd Street, New York, NY 10019. It is available at the Paley along with the three other television specials that he made from 1958 through 1968.
Unfortunately, for unknown reasons the holder(s) of the legal rights to these TV specials have not made them available for reissue onto commercial DVD. Fred's many admirers---and all lovers of great dancing in general---should post on IMDb their objection to this situation on behalf of every person who appreciates fine art, timeless entertainment and superb dancing by the greatest master of popular dance to have ever appeared in film.
The names of these TV specials as they appear on IMDb are "An Evening with Fred Astaire"(1958); "Another Evening with Fred Astaire"(1959); "Astaire Time"(1960); and "The Fred Astaire Show" (1968).
