I went in 2006 and 2007. Good sessions in "Old Tom" pub,near Carfax,& a Sunday lunchtime French session in "Far FRom The Madding Crowd" down an alley near Watersons----but the venue might have changed now ! Best sessions I guess are /should be in the "Half Moon" (go over Magdalene Bridge, bear left),----could find Ian Giles,Les Barker, et al in there.Oxford Castle is good & now a venue for dance displays.Best bet is to find Bill McKinnon and follow where he goes !!
