The incident was telecast live on Sri Lankan television.
Wijemuni, now bearded, wearing spectacles and balding, sits in a shop in Nugegoda supermarket.
Asked about his predictions for the Mahinda Rajapaksa government, Wijemuni, who contested elections under the ultra-nationalist Sinhala Urumaya party in 2000, says Rajapaksa will not be president after the next elections.
Wijemuni said: "Rajiv Gandhi tried to create a separate state...that was wrong. He was unjustified, so it was natural justice. If Rahul Gandhi wants to be PM, he should not strive to make a separate state here."
The man says he sells Hindi music because he loves Hindi film music and Indian classical music.
Wijemuni said he has "no vengeance towards India", but it was wrong for the powerful to threaten the sovereignty of others.
