Looking for the font of Cadet Concept record label from between 1967 and 1970

[Hindsight]

Hi there,

Apologies in advance - I’m a complete typography novice but stumbled across this incredible forum while looking to identify the font used on a series of Cadet Concept Records in the late 60s. 
 

I’m looking to identify the font used for the name of the label itself, which is in pink and orange in the attached example (a record by Muddy Waters). 
 

Cadet Concept was a record label based in Chicago between ‘67 and ‘70. Other releases with a similar style font include The Rotary Connection (featuring Minnie Riperton) and examples can be found here: https://www.discogs.com/label/52986-Cadet-Concept

Any ideas or suggestions as to what font is used would be thankfully received. 
 

Thanks in advance.

I’m afraid it’s a custom logo, not a typeface.

Thanks so much for the reply, Riccardo. Very helpful. Do you know of any similar fonts?

I have looked for something comparable, but haven’t found anything both blocky and “groovy” as the sample.

No worries - many thanks for trying. Much appreciated.
