Musical Recital - Logic Puzzles

At a musical recital five students (John, Kate, Larry, Mary and Nick) performed five musical pieces. Two by Bach, two by Mozart and one by Vivaldi. There were three violinists and two pianists.

The composers were not played consecutively. Vivaldi was played last and Mozart was played first.
There was one piano piece that was played between two violin pieces, and two violin pieces between the first and last piano piece.
There were no piano pieces by Mozart.
Kate played third.
John played a piece by Mozart, and was immediately followed by Nick, who played the piano.
Mary did not play a piece by Vivaldi.

Puzzle 527 



This BrainBashers safe has a rather unusual control panel.

In order to open the safe, you have to press every single square once only, in the correct sequence, ending on the square marked E.

Each square indicates which square to press next, for example, 2U means move up 2 squares and 3R means move right 3 squares.

Can you determine which square you must start with?

Note: this puzzle is not interactive, and the safe buttons cannot be clicked.

Puzzle 528 



I was travelling from Chesterton to Newcastle recently when I came across a sign which had fallen off its post at the crossroads.

It was marked to Newcastle, Chesterton, Knutton and Silverdale.

Unfortunately I didn't know which road to take to Newcastle and had hoped the sign would help.

Luckily I had a brainwave which helped me put the sign back pointing correctly to Newcastle.

What was my idea?
