£65 is comparatively a bargain for a concert by a global star like Lionel Richie.
In the past few weeks I've bought tickets for 3 concerts and a festival
Peter Hook (ex New Order) £20.12
New Order £35.00
Elbow £42.50 (this is a special event at Jodrell Bank observatory)
Latitude Festival £188.50 for dozens of bands, comedians, readings etc over three days
I suppose the final decider though is if you think it's worth it - how much do you want to see him live, and will he likely play concerts again in the near future.
