Insect id requested--Catoctin

["Greg Weddig" gweddig]

So I have tried using Lang and Wil's book, The Sounds of Insects (which
I think is  fantastic!) for the three calls on the recording below.  One
I believe is the oblong-winged katydid (the creek...creek).    They were
recorded the end of September at Catoctin Mountain Park in northern
Maryland, US.

The other two I can't figure out:
  a large chorus of southeastern ground crickets?

The chee-chee-chee......chee-chee could be a common true katydid, but
again I haven't developed my ear for these calls yet.

I can't post a smaller version of this until this evening, sorry to
those with dialup.

Thanks,
