A US jazz band have become internet stars after performing in France to an unlikely audience - a herd of cows.

Video footage showing The New Hot 5 performing to a field of cows in Autrans has already had more than 270,000 hits on YouTube since it was uploaded last week.

When one of the members of the New Orleans-style jazz band started to play When The Saints Go Marching In, the cows walked up to him.

And by the time the rest of the band had joined in, the whole herd was gathered in a line seemingly enjoying the music.

The New Hot 5 ensemble, specialize in the music of Louis Armstrong, Sydney Bechet, Jelly Roll Morton and other classic jazz legends.
