Shiv Sena defended cancellation of Ghulam Ali's concert, under attack from political and cultural quarters. Shiv Sena's youth wing chief Aditya Thackeray said, it was not possible to have fun when soldiers are being martyred and it will continue to "boycott" Pakistan till it stops terror activities.<br/><br/>Ghulam Ali's concert planned at Shanmughananda Hall for tomorrow was cancelled last night, after Shiv Sena threatened to disrupt the show. Ali had earlier performed in Mumbai as a tribute to Jagjit Singh along with several singers from India.
