"Hello My Old Friend" and "Mandalay" [still] can only be found on the 1990 US 3-CD release "Afterglow" [#Z3K46090]. "No Way Out" can also be found on "Afterglow" but was also included as a bonus track in the 2001 re-release of "Secret Messages" [#5024962]. "After All" was the 'B' side to the single "Rock & Roll Is King" [#A3500] and can currently only be found as a bonus track of the 2001 version of "Secret Messages". "Buildings Have Eyes" was the 'B' side to the single "Secret Messages" [#A3720] and can only be found on "Afterglow". This is where it gets a little complicated! "Endless Lies" turned up on the 1986 release "Balance Of Power" but it was not the 'original' version ... this was slated to appear on "Secret Messages" and that 1983 version was the third and final bonus track on the 2001 re-release of "Secret Messages".
So there you have it! Six tracks; two released on vinyl as 'B' sides; four from "Afterglow"; three from "Secret Messages" ; one track released twice as alternate versions; all six available in some form on CD ... all except, of course, for "Beatles Forever"!
By the way; "Secret Messages"  misses out the 20-30 seconds of 'secret messages' at the end of "Rock & Roll Is King" on the LP and original CD release [#4624872].
So now you know how to gather seventeen out of the eighteen tracks of the originally intended "Secret Messages" double album. Yours Truly KJS will address this in more detail later but next time it'll be time to investigate "Beatles Forever" a little more closely.
Until next "Time" in the ELO [and related] Universe ... KJS ... 07-Feb-2009
