Earl Grant??? Anyone remember the 60's?

In the mid 60s I used to listen to a jazz station late at night and remember a tune by Earl Grant (???), keyboard only, no vocal and it had airport tower radio traffic superimposed over it. There were at least 2 different Earl Grants, makes it hard to find anything. Also could have been Erroll Garner, but his stuff doesn't sound like it either. I can hear it in my head but can't find it. Not sure of the artist, don't know the name of the tune. Any ideas?
