Thanks for correcting my brain fart, pdq. I know Suze's grandfather was Tim Spencer. Marshall is her married surname.
(If a Mudelf sees this and can correct Tim's name in my post, it might help prevent that mistake from spreading.)

A lot of what Suze has been doing over the past decade or so is working to reclaim and record some of the songs that Bob Nolan wrote or co-wrote and performed with the Sons Of The Pioneers for the movie studio (RKO?) but were not allowed to either release as records or to perform professionally, because the studio that owned the rights did not release some of those movies and would not release their rights to the music.   So some of what Suze has recorded consists of never-before publicly released Bob Nolan/Sons Of The Pioneers songs.   

I almost never pay $20 for a newly released CD (unless it's a double), but in this case I think it's probably worth it. And you're not likely to find this CD at thrift stores or used record/CD stores.
