Likely candidates (can't be absolutely sure they were the LAST, but...)from me:

Roseville Fair / Bill Staines
Arrow / Cheryl Wheeler
Blue Umbrella / John Prine
Matt Hyland / Trad ?
Water is Wide / Trad ?
Slow Down / Kevin Mulvenna (a local s/s friend)
Lying to the Moon / Matraca Berg (via Robin and Linda Willaims)
Circle Game / Joni Mitchell
The Boy With The Moon and Star on his Head / Cat Stevens
(Which just might get to claim that "longest title" Bruce from Bathurst was looking for)

and almost always end with Amazing Grace
