Segovia's version wasn't formally published, but there are photocopies floating around (or were in the 1970s) of various selections which people had transcribed by ear off the LPs.
There is/was a great story of the whole publication background posted on the RMCG Usenet list in December 1999, by Angelo Gilardino. Basically, Gilardino wanted to publish Tedesco's version as-written, and Ron Purcell wanted to publish the as-played-by-Segovia version. Gilardino won the day, and the four-volume complete cycle was printed as-written. In Gilardino's words, this grants each performer "the dignity of being his/her own editor, and no longer thought of as an irresponsible child who needs his/her parent's assistance for walking around." The downside of course is that there are any number of places where Tedesco's original writing is damned near impossible to play, so editing is needed, and playing directly from the score is out of the question for all but the very elite among CG sightreaders.
The same thing happened with other well-known pieces in the 1960s/70s. The published edition didn't align with the recorded version, so pirate photocopies were passed between students freely. Torroba's "Burgalesa" (published in F# major, but generally played/recorded in E major) is a classic example, along with the Platero cycle.
