The following 2 sites are designed for 78-rpm record collectors, and they both have discussion forums. You might try asking there. (I found them because Scrappy Lambert has already been mentioned in them.)

If you ever find the lyrics you want, please come back and post them here. Also any specific information like record label, year, band name, etc.
