Well its worth a try, isn't it?
"Happy Day From Me To You" - Sir Victor Uwaifo
"Happy Beat" - Joe Mensah
"The Happy Song" - The Twinkle Brothers
If that doesn't do the trick, something else you could do to try to cheer yourself up is to tune in to some of the live streamed online concerts that musicians are putting on to compensate for cancelled live gigs. It doesn't match the real live experience - you will actually be able to see and hear them properly, and where's the fun in that? - but on the other hand its a chance to see some acts that might not otherwise have been round your way any time soon.
There are a couple of online gigs this weekend that I will be watching by folks we've featured here before: Dori Freeman on Saturday and Asthmatic Harp on Sunday. Click on their names to get the details, and remember to pay an entrance fee.
And if even that doesn't cheer you up, there is always Gilbert.
