WTB: old audio casette with urban background sounds

[IndyCity]

I need your help.

Until about 8 to 10 years there were C60 and C90 audio cassettes with typical urban or landscape sound as background sound.

I hope serveral of you will remember them.

I think Green Frog would have offered thses casettes.

It may also have been several manufacturers.

I'm looking for such a casette with urban sound for my layout.
