[78-L] 78s and 45s of Texarkana Baby by Eddy Arnold

[agp]

I'm trying to put some facts around the release of Texarkana Baby/ 
Bouquet of Roses by Eddy Arnold as a the 1st 45 from RCA. Actually 
its more facts about the 78, than the 45.

I had thought that they were simultaneous issues. But I seem to be 
finding out that the 78 was released in 1947, the 45 of course in 
1949. Is that 1947 date true?

So what was the first simultaneous release on 45 and 78?

Obviously RCA had to have done some test pressings prior to the 
release of the 45. Does anyone know what they were? I have seem a 
demo record for stores in blue vinyl, but nothing else

Finally, what was the sleeve style for RCA Victor 78s when Texarkana 
Baby 78 came out? Was  it the one with red print that touted the 
'triple difference

Finally -- which is the real A side!

Thanks
