1982 hit "Twilight Zone." But this Dutch group had a long string of hit singles and albums in Europe, especially in the Netherlands. The first version of the band started in 1961, and the lineup you see for that cover of Seven Tears was together from 1970 through 2021. They broke up early last year only because lead guitarist and founder George Kooymans had been diagnosed with ALS.
I just posted the hit single from this album in another thread here: https://democraticunderground.com/103481008 .
I've posted a lot of their music here, and I compiled a list of links a couple of weeks ago for another DUer who wouldn't have been able to search the forum for those thread titles (unfortunately only Star members can use that search feature, but Star memberships are for any size donation, and the extra search features, including the Advanced Search in the upper right corner of every page under the Google search, are really useful at times).
Here's a link to the post with that list of posts with some of Golden Earring's music:

Re what you said about "21st Century Schizoid Man" - I can hear those hints, too, though that hadn't occurred to me before, and I've never seen that mentioned by any Golden Earring fan discussing the album in any discussion I've run across online. Bands had so many influences then.
I ran across a web page the other day with a readers' poll done by NME (Britain's New Music Express) at the end of 1973 that had "Radar Love" as the top non-British single and Golden Earring as the most promising non-British artist. But the band's musical influences and styles were so diverse that they weren't easy to market in the US, and they didn't like doing long tours. They also got censored by MTV and weren't happy about that.
Jimi Hendrix tried to hire their bass player. The Who wanted their drummer, Cesar Zuiderwijk. All of them have had side projects with some success, and George Kooymans has helped a lot of other artists' careers with his songwriting and producing. They're so popular and respected in the Netherlands that on March 11 of last year, George's birthday, just weeks after the news about his illness and the Earring disbanding, both radio stations and church bells all over the Netherlands played "Radar Love" at the same time, at rush hour (and of course fans did, too).
