Times Jumbo 675

[Annie Jay]

Nearly there, but stumped by 2 clues.
49ac 'What will make son soon participant in piano duet?' (7) ??C?N?O
47dn 'Spots two of the four players at table having food' (6) ???A?S

That's assuming 53ac is right. 'Martial art from Asia - I don't take part' (3 - 2) AKI-DO? (Aikido minus I?)

Wonderful, K! I've sent a reply before, but the AB site crashed & I realise you've not received it. I'd got secondo & espies, but the martial arts one confounded me despite a great deal of Googling. Pity the Answer Bank don't do 5 star ratings as you 'd qualify every time! Sunday Times was a doddle, but not complaining as it's been a hectic period for those of us less skilled than you. Still got Jumbo 676 to do. Happy New Year!
