Calling Ideas for July 29, 2012

This is:

Randy Sparks' Birthday
Folk singer, songwriter: groups: New Christy Minstrels: Green, Green, Saturday Night, Today; The Back Porch Majority, Randy Sparks and the Patch Family

I know there's a Green, Green singing call, 'cause I have it. One might also take advantage of this week being National Salad Week when introducing the song....

The Fourth week of July is:

National Salad Week
Hmmm...maybe songs about green? (Green Acres (part of Theme Time)), Green, Green,Green, Green Grass of Home

July is:

National Hot Dog Month
National Ice Cream Month
Hitchhiking Month
Road songs
National July Belongs to Blueberries Month
Must be blueberry season; time to eat a lot of blueberries.

Can we say "Blueberry Hill"?

There's also a Nitty Gritty Dirt Band instrumental called "Bluesberry Hill" that a lot of callers are using for patter.
