Sounds like it's pretty hit and miss.
For me, some of Dee's stuff since TS has been OK - Desperado and Widowmaker, some of it pretty average - Widowmaker, and some surprising - the Mack The Knife which I really like. Then there is his other 'solo' stuff like Love Is For Suckers, which is excellent, and Heroes Are Hard To Find, which is probably his best song IMO.
If there are a few great songs I'll be happy.
