Gift for 70 year old Woman

[Willowback]

I'm tasked every year with picking something up for my dad to give his sister - why he doesn't get his partner to do this I have no idea she's nearer her age!!
I have in the past got her candle gift sets which have always gone done well. I'm looking to spend £40ish and I have bought her a lovely scarf so it can't be that.
Any ideas??

Tickets for a show? Who does she really like? Does she like music? There are a lot of 70s bands playing ATM. Comedy? (And local venues are reasonably priced rather than the West End) I'm 73 and that's what I'd want. If she hasn't got a partner, tell your dad he'll have to go with her!
