Bill Bragg, Kate Nash and Get Cape perform reduced G20 protest set

Musicians hoping to join the G20 protests at the Bank Of England in London today (April 1) have been frustrated in their efforts.

As previously reported, the likes of Billy Bragg and Get Cape. Wear Cape. Fly performed at the G20 Meltdown's "Financial Fools Day" protest.

The performances eventually took place shortly before 1pm but were scaled down because the square around the Bank Of England was cordoned off by police, meaning it was impossible to get a suitable sound system to the performers.

Our reporter who was in crowd at the protest said that Bragg, Nash and Get Cape. Wear Cape. Fly's Sam Duckworth played several songs acoustically for the protesters who were inside the cordon.

Enter Shikari's Roughton 'Rou' Reynolds was also among those being contained by police, although the crowds are now being allowed to leave.

Meanwhile, a branch of the Royal Bank Of Scotland adjacent to the protest was broken into by a small group on the fringe of the march.
