McGrath said it - "keep playing together for its own sake" - that's what the musical process is all about.There may be no immediate money, accolades etc, but the time you play together is all so valuable for the future.
None of the "pre Pete Waterman" bands ever had instant recognition or success - they walked the boards and strutted their stuff for years whilst learning their trade.
Just keep doing it and don't stop.
Cheers, Terry
