Ernie Lucas
Ernie Lucas’ two 45s for Okeh are among the least heralded from this best loved of Chicago labels. But his expressive tenor vocals are worthy of much more attention. His own uptempo 
Nothing Can Separate Me From Your Love with it’s lovely bluesy cadences is a fine slab of hard West Coast music and really recommended. The flip is a more mellow “What We Pay For Love” featuring some very tasty guitar licks. His other first class track is the similarly paced Love Thief which has a really strong arrangement to match the melodic chord changes.
UPDATE ~ Bosko Asanovic has kindly been in touch with more details of Ernie's recordings as "Arin Demain" and "Karl Evans" and other pseudonyms - these have been added to the discography. Thanks as always to Bosko for his knowledge.
