Caught northern Spice Girl draped in curtain, making church music (6,7)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

A charade of C (‘caught’) plus HANGERINGING, an envelope (‘draped in’) of N (‘northern’) plus GERI (Halliwell, ‘Spice Girl’; her nickname, Ginger also makes an appearance as an anagram – not that that has much to do with anything) in HANGING (‘curtain’).
