Lisa and Jean have another album of similar songs called "Anywhere Is Home". Album contains: Turn Your Radio On; Standing ON The Promises; Life's Railway To Heaven; Let The Lower Lights Be Burning; Grey Funnel Line (not exactly old time gospel); Run Come See Jerusalem; Near The Cross and others. Interestingly, their collection of backup singers calls themselves The Angel Band.
A nice version of " Angel Band" can be found on the EmmyLou Harris album of gospel songs by the same name.
Looking for old time gospel songbooks. ONe you might find is :" Albert E Brumley's Olde Time Camp Meetin' Songs" c 1971, Camp Meetin' Song Book, 342 West Hiwy 54, Camdenton, MO 65020. It is a paperback with 60+ songs. Among them are: Beautiful Isle of Somewhere; Bringing In The Sheaves; Diamonds In The Rough; Farther Along; I'll Fly Away; Nothing But The Blood; Precious Memories; Softly & Tenderly; Great Speckled Bird; The Old Time Religion; Picture From Life's Other Side; Royal Telephone; Unclouded Day; Where The Soul Never Dies; Never Grow Old; many others including on p23 O Come Angel Band.
I bought my copy in the last 10 years at a Minnesota State Park gift shop so it may still be around.
A book with 184 songs, but maybe harder to find is: Rodeheaver's Gospel Solos and Duets. c 1925 Rodeheaver Co., Chicago This one was my mother's
Also: Tabernacle Hymns Number Three, c 1934 Tabernacle Publishing Co. Chicago. This one has 350 songs in it. I presume there was a Number 1 and 2 in the series. The title page says "Printed in round and shaped notes", but there ain't no shape notes I can find in my copy so there may have been two separate printings.
