Search library music in the style of the 70s

[Franz Münchinger]

Hi!

Does anyone know the name of this piece of music from this video?

https://www.youtube.com/watch?v=kNvBVKqRK34&t=165s

It starts at 1:48 and ends at 3:00
It sounds 70s style. Maybe it's also royalty-free?
I have another audio recording where you can hear it better and longer, but I don't know how to upload it here
