With apologies for the short notice, tonight's episode of the BBC Radio 4 show, Front Row, includes an interview with Roger Waters and Nick Mason.

With the BBC's London offices a literal stone's throw from the site of the plaque unveiling this morning, at the University of Westminster on London's Regent Street, it is no surprise that they caught up with Roger and Nick on this special occasion. Having already heard the interview, we think you will enjoy it!

Front Row airs on the UK's BBC Radio 4 at 7:15pm BST. For those unable to hear it live, the show will be available in full on demand after broadcast. More information can be found here: www.bbc.co.uk/programmes/b05w4jdb.
