We did exactly this in late 2008.
We disbanded in about 1991 for what we thought was the final time.
Our guitarist put together an album from old demos that he rerecorded with his brother, some of his friends and our singer in 2002 and released it under our name.
A few of these were pressed on CD and sold slowly.
An American fan maintained a web presence for us by keeping sadloversandgiants.co.uk alive.
In 2008 we got a message via the website from an Italian promoter wondering if we had considered gigging in Italy.
There was also a message from a Greek promoter asking us to play there.
We hadn't really spoken with each other for many years.
The singer and the drummer had kept in touch, the guitarist had become a global superstar DJ and the keyboard player had moved to Santa Monica USA.
Despite this we reformed the band with a different keyboard player and have been active ever since.
It's so much better this time around - we only play a few gigs a year but get together many weekends - we spend most of our time together in restaurants, stuffing our faces.
We have played all over Europe and in the USA and put out an album in 2018. We are recording another now.
There's no pressure this time round and it's a lot of fun.
Edit: I forgot to mention that in 2002 or was it 2003 the singer, guitarist and drummer got together without me but with another bass player from the band's history (both before and after my first time around) for a one off gig in Rome. Apparently the bass player got very drunk and pissed off the guitarist which put an end to that incarnation.
