[78-L] Anybody know what year Aladdin quit pressing 78's?

[Robert M. Bratcher Jr.]

R&B label from the 40's & 50's. I'd like to find all of the Shirley & 
Lee releases on both 78 & 45 RPM but I don't know what year that 
Aladdin stopped issuing 78's.

I've got Aladdin 3298 Feel So Good/ You'd Be Thinking Of Me on a near 
mint 78 found at a record collectors show plus a very worn (lots of 
hiss) 45 that I bought used many years ago. That 45 was the first 
record of Shirley & Lee that I ever found. One day maybe I'll find a 
better copy of this 45.

Have the 45 RPM version of  3325 Let The Good Times Roll/Do You Mean 
To Hurt Me So but I don't know if a 78 RPM issue of this was released 
as I haven't found one.

The Both Sides Now web page has the discography I need for all the 
songs released by the singers. All I have to is find them through the 
bay & perhaps other sources. Before I put up a want to buy ad on the 
bay I'll need to know what year the Aladdin 78 stopped. 1956? 1957? 
1958 maybe? I doubt it was 1959 however it might be possible.....
