Music used in Kojak episode ?

Hi,

I am writing 'cause last week I saw Kojak episode 'Pilot' in one of the scenes Kojak have put an LP on gramophone and the music was really beautiful !! All I could see was Delphi Trio and the collor was green !? I tried to found out something about 'Delphi Trio' but couldn't find anything !!

Is there anyone that can give me more info or know where to write to found out about this music and who is the performer !?

Thanks in advance and brgds from Slovenia !!!
