I have just become aware of a site that has posted some more unreleased material by Mandrake Paddle Steamer/Mandrake.
Check it out here:
Three new songs, and some possible upgrades to tracks on the "Overspill" LP
Definitely worth a visit to hear the delights of "Stella Mermaid" and "Doris The Piper"
and a rather later track called "Nice Man" from 4/3/70 when the band were known as "Mandrake"
We have Terry Morley to thank for this new insight into the band. Hope there will be more to come.
The British Music Archive site also had some useful info on the band. However as of today the site is crashed.
