Yep - a pink plying-vee ukulele. Seen above taking a starring role with the great Roger Ruskin Spear and newly invested Bonzo Adrian Edmondson as they do the Trouser Press (baby).
Here's a couple of other shots showing the coolest instrument on Earth with legendary Bonzo celebrities. Firstly, Roger Ruskin Spear from the waist down on the chair and "Legs" Larry Smith:
Needless to say I adore the Bonzo Dog Doo-Dah Band, have done for more years than I care to admit. The new album's a cracker, they're still every bit as silly and they're still marvellously inventive musicians and writers. If any of the fine gentlemen who make up the band happen to stumble upon this, my apologies for using images to which I have no rights whatever, except that I think you may have borrowed my ukulele.
