That was Wolverine Radio. There were some technical glitches so you may have missed the IDs, which tend to be fairly low key and subtle. Here's my log, copied from FRN:
5/10/09
6925 USB
0117z: Patsy Cline "Walking After Midnight", followed by jazz swing I don't recognize
0126z: Wolverine Radio ID
0128z: Suddenly off mid-song, some kind of glitch
SINPO - 34223, very good audio, some fluttering fades but intelligible throughout 'til signal dropped.
0133z: Back up. Weaker now, sounds like more jazzy/bluesy swing.
0134z: Either fading to inaudible or off again.
0136z: Clear Wolverine Radio ID after a couple of minutes of silence.
0138z: Back again with more jazz swing. Don't recognize any of it but sounds good.
0142z: Sounds like instrumental version of "It Had To Be You" with vibes and clarinet.
0146z: Wolverine Radio ID on top of segue into "Putting On The Ritz" (I'll never be able to hear this song without thinking of Peter Boyle in Young Frankenstein.)
0154z: Sounds like Louis Armstrong
0156z: "Minnie the Moocher". Hidey-hidey-hi!
0158z: Wolverine Radio ID
0207z: "I'm In The Mood For Love" - continuing with good signal peaks, some fades, heavy local RFI but music is cutting through the noise.
0220z: Wolverine Radio closing ID w/ echo fx
SINPO - 31222, some good peaks but regional static crashes heavier now and local RFI up.
