'Swami Haridas Sangeet Sammelan' is held every year at

Concept: A named classical or light-classical music festival (a "Sangeet Sammelan") is instituted and organised by a specific city's cultural body in honour of a musician, and it continues to be held in that institution's home city year after year. Identifying where such a festival is held means identifying the host institution's city, not merely where the honoured musician lived or worked.

Application: The Swami Haridas Sangeet Sammelan is one of India's oldest continuously running Hindustani classical music festivals. It is organised every year by the Sur Singar Samsad, a Mumbai-based cultural association, and has been held in Mumbai since 1952 in honour of the 16th-century composer-saint Swami Haridas, the guru of the legendary musician Tansen.

Cross-check (why the other cities do not fit):

• Agra falls within the Vrindavan-Mathura (Braj) region that Swami Haridas is historically associated with, but the Sammelan bearing his name is organised by a Mumbai-based institution and held there, not in Agra or elsewhere in the Braj belt — the honouree's own regional association is not the same as the host city of the memorial festival.

• Amritsar's defining cultural landmark is the Golden Temple (Harmandir Sahib) and its Sikh devotional-music tradition; it has no connection to this Hindustani classical Sammelan.

• Jodhpur is known for its own desert and folk-music festivals, not for hosting this particular Hindustani classical event.
