Seeking Rodeo Recordings

I am very interested and actively seeking recordings of the following:

ZZ Top - Houston Rodeo - 2007
ZZ Top - Houston Rodeo - 2009
ZZ Top - Houston Rodeo - 2012

If you have a recording or can help me obtain one I am willing to trade up to 10 shows, memorabilia, official merchandise, currency, whatever.

Any help is greatly appreciated. Thank you.
