This strikes me as a very odd choice for hirez. A live 70's rock concert, not tremendously recorded in the first place. I attended this tour; great stuff but...24 bit? C.mon. I wonder if the studio overdubs (because of out of tune backups) will be hirez too.

The video, Rockshow, has been recently remixed for 5.1 and maybe might be fun...
This album, however, was due to be re-released, as it had been over four years since doing the last time (for like the 8th time).
From wikipedia:
Wings over America was another success for Wings, reaching number 1 in the US in early 1977
The album was repressed a month later, in January 1977
It was issued as a double-compact disc in 1984 on Columbia
The album was first released in the UK on compact disc on 26 May 1987 by Parlophone
The album, along with McCartney's Ram and Tug of War albums, was reissued in the US on compact disc on 18 January 1988
The album was issued by EMI two more times on CD, in 1989and on 19 February 1990.
A 1999 reissue of the album by Toshiba-EMI in Japan reinstated the three-disc format from the original LP issue, and is the only edition of the album to do this.
On 14 April 2008, the album was released as a digital download on both iTunes and Amazon.
It was removed for some time off of digital music sites in 2010 and 2011, but as of August 2011 it is available for sale on iTunes.
The album was reissued on 27 May 2013 as part of the Paul McCartney Archive Collection.
Rockshow will also be reissued, this time on DVD and Blu-ray, with its audio remixed into 5.1, on 10 June 2013.
And that's not even mentioning this new hirez version, wherever the heck it cam from.
I love Paul! I really do...but c'mon!!!!!!
