CAN THIS BE CURED? [Sleepwalk?] (1984) V2000 Cassette

This recording came from an old "Grundig V2000 Cassette". Unfortunately I don't have access to a Fully Working V2000 VCR anymore. So the only option is to somehow Correct the "Visual Flickering" with some sort of Software. I'm not smart enough to know how to do this I'm afraid. :-)
The guy doing the Robotic Dancing used to be on Top of the Pops in the Early-Mid 1980s quite often. Be nice to see this again without the picture Twitching all the time. This was recorded from some Variety show in 1983/1984 on BBC, ITV or CH4.
