Well, not records, really: tracks.
I've been going through my collection database, creating a version which contains only the official (and a few unofficial but legal) releases over the years. I have included all EMI and Rollover recordings, with studio versions and live versions counting as separate tracks. As an example, there are eight (8) separate versions of Apache, listed:
1960 EMI studio version
1964 Live In Holland (with John Rostill)
1969 Live In Japan version (with Alan Hawkshaw)
1975 Paris Olympia (with John Farrar)
1978 Live at The London Palladium version (with Alan Jones and Cliff Hall)
1989 Rollover re-recording
1989 Live In Liverpool
1990 Shadowmix version (an edit of the Rollover re-recording).
Apache provides an example of the varying laws on copyright which have existed in Europe. I have included the legitimate-in-Italy releases from Aulica and Fremus in my total.
So... including studio versions, re-recordings, live versions, alternative versions and different mixes and edits....
...I make it a total of five hundred and sixty-eight (568) tracks, from the live versions of Jet Black, Driftin' and Be-Bop-A-Lula in February 1959 through to Life Story in 2004.
One of the 568 which I don't have in my collection - yet - is the "Green Mountain remix" of the Rollover Wonderful Land. But I'll work on that one.
Any competing totals?
