Liverpool Former Players Association (they call themselves that on their Charity page), organize LFC legends appearances and signings with paid attendance, also available for charity events:
https://5times.co.uk/events/Mostly in the UK (see above link), but some overseas appearances coming up:
Carra in New York 11/12, Chicago 11/13, and Toronto 11/14
Fowler in Adelaide 11/9, Brisbane 11/10, Melbourne 11/11, Sydney 11/12, and Perth 11/16 in Australia and Wellington NZ 11/14
That's an unfortunate name for the organization, I mean they're going to have to get a whole new domain when we win number 6 and onwards
