This is a bass solo type thing that I use when I warm up sometimes... I am not at all certain where it comes from, if it's actually a famous song or just me doodling around with something I've heard a million times (one of my other favorite warmups is "Die Erlkonig" for example ☺) but at any rate here you go. Happy Birthday!
NOTE: The guitar part is "recommended weakly", i.e. it's actually kind of an arrangement for vibraphone and can DEFINITELY be improved upon. But it helps the simulator that is generating the recording to have a harmonic reference and so there it is in print.
