Grand Prix in 1976. The recordings are in Mono (sorry), 16 bit and 22KHz.

The
Lauda accident. 
(The picture is borrowed from the official Nürburgring-site.)
This is what first got out on the speakers when Niki Lauda had his
terrible accident. The crowd reacts with boo's and whistles that the race is stopped
because Mass (German, remember) is in the lead. And no one knows just what kind of
accident it is.

commentator. 30 sek. Microsoft ADPCM compressed format at 336Kb
