The Cats had style. 36 singles in the Dutch Top 40, 19 of them top 10 hits and 5 number 1 songs. And great live performers.
Luv not so much, but they had the looks and legs.
Here is a real big one in Europe from the past, with an encore at the end of a show. He always did that in his white bathrobe.
Always the same medley with a some of his hits.
Well Luv was build around the simple and well functioning concept sex sells, and they had enough commercial success. Some nice, catchy tunes, they never hurt anybodies feelings and clean image, so a nice fluffy scandal free feel good band with matching music, which everybody likes to enjoy now and then.
Udo Jürgens was one of the living legends and giants of the German music scene. He always sung live, wrote most of the songs by himself and was able to perform on the grand piano. Also his lyrics often were quite critical about certain topics, like double standards and so on. And he sold over 100 million records, which is a lot!
By the way the white bathrobe became a tradition in his live shows because in 1969 he want on tournee throughout Europe starting in Hamburg. The concert was already over since 15 minutes, but people were still cheering for an encore, so Jürgens left his stage room robe just in a white bath robe and delivered it. Since then it was a tradition on many of his live concerts.
One his English songs named "The Music Played", the German version is "Was ich dir sagen will." That song though was made popular by Matt Monro in the English world, but Jürgens is its creator.
Same song performed by Matt Monro:
There's also a Spanish, Greek and Finnish version around. Probably many other languages as well I am unaware about.
